The Sun continually ejects matter into space, blowing a huge bubble of supersonic plasma. This solar wind bathes the whole solar system and shapes all planetary environments. The growth of space technology has considerably increased our knowledge of this medium. This 2007 book presents an introduction to the subject, starting with basic principles and including all the latest advances from space exploration and theory. It contains a short introduction to plasma physics and discusses the structure of the solar interior and atmosphere, the production of solar wind and its perturbations. It explains the objects of the Solar System, from dust to comets and planets, and their interaction with the solar wind. The final sections explore the astrophysical point of view. The topics are treated at various levels of difficulty both qualitatively and quantitatively. This book will appeal to graduate students and researchers in earth and atmospheric sciences, and astrophysics.

The large telescope at Meudon has become legendary. When it was conceived, after 1870, astronomy as a whole was limited to visual observation. Knowledge of the sky was limited to what one could see, assisted only by optical means. The large telescopes produced at this time produced larger images, permitting close-up views: the Meudon telescope was able to accomplish this perfectly. At Meudon, which became the Mecca of visual observation, the major planets were examined in a way that no other telescope had previously been able to. The telescope monitored the state of their atmospheres and mapped the appearance of their surfaces. Through the telescope, one could obtain photographs showing the nuclei of comets, revealing their very small size, and by using an eyepiece one could measure the separation of double stars. With a marvellous little instrument, the polarimeter, the nature of clouds in planetary atmospheres has been determined, and the type of surface material identified. Many more results were obtained, while photography, universally adopted, revolutionized other knowledge about the world. The sensitive emulsion, combined with large aperture reflecting telescopes, revealed the deepness and richness of the cosmos. The vast telescope of Meudon, which was the largest refracting telescope in Europe, became a legendary instrument and was symbolic of a new way to practice astronomy. Audouin Dollfus, a renowned astronomer, describes the great years of the Meudon telescope. He gives us the entire story of this instrument, from the birth of the concept that drove Jules Janssen at the end of the nineteenth century, to the idea that French astronomy could provide an outstanding telescope which would approach the limits of technical and industrial resources. The telescope remained unchanged until 2006, when the first steps toward restoration and public reopening were taken.

The book is an up-to-date, concise presentation of the development of submillimeter-wave and far-infrared astrophysics. The topics range from the large-scale atomic and molecular distribution in the Galaxy and in external galaxies to the frontal properties of molecular clouds and the details of the star-formation process. A chapter on the most recent technical advances in the field illustrates the intimate connection and interplay between scientific advancement and technological capability. The book not only summarizes the advances in the field but also presents important background information, addressing experts and graduate students alike.

The rapid growth in our understanding of how stars form owes a lot to recent developments in techniques for carrying out infrared and millimeter-wave astronomy. Thus Star Formation and Techniques in mm-Wave Astronomy were natural joint themes for the Fifth EADN Predoctoral Astrophysics School held at the Technische Universitat Berlin. The lecture courses by six world-class experts are aimed at postgraduate students and scientists with a non-specialist interest in the field. Topics include molecular clouds, T Tauri stars, OB stars, observation methods in infrared and mm astronomy, as well as high resolution techniques.

This symposium was dedicated to science opportunities with the VLT. All major areas of astronomical research were discussed in the plenary sessions, ranging from where we stand in cosmology to the new frontiers in the solar system. The workshops published in this volume focussed on different ways of finding clusters of galaxies at high redshift, on gravitational lensing by distant compact clusters, on the use of stellar populations as distance, age or abundance indicators, and on the extraordinary progress made in the discovery of extrasolar planets. This book affords a glimpse of what will be at the center of astrophysical research in the forthcoming decade. It is addressed to researchers and graduate students.

In seven lectures of a pedagogical nature aimed at both researchers and graduate students the authors review important aspects of hadronic physics. The book contains a comprehensive review of recent experimental results obtained at the GSI collider. In particular, it covers chiral symmetry at finite temperature and statistical methods applied to relativistic heavy ion collisions and gives a detailed presentation of the astrophysics of strange quark matter.

To get a reasonably realistic picture of the structure and evolution of stars one needs to know accurately the abundances of chemical elements and their isotopes in the stellar atmosphere and in the galactic environment of the stars. The articles collected in this volume give a modern review of the abundance accuracies for main-sequence stars. After a general introduction in the first part the accuracies of atomic transition probabilities, ionization and excitation cross-sections, and line broad- ening data are discussed. In the second part the specific problems and results for different stellar types are presented, and, finally, an overview on the possibilities of abundance determinations for stars outside the Galaxy is given.

This book will certainly be considered an important reference for astronomers and astrophysicists handling large amounts of data in observational and theoretical approaches to the large scale structures in the universe. The contributions are written with an emphasis on methods. The volume contains among many other topics recent observational results on redshift surveys of clusters and distributions of galaxies and quasars, together with articles on the importance of these findings for future standards and for theoretical predictions. A long historical chapter serves as an introduction. This mixture of textbook and review is aimed at the newcomer to the field as well as at the specialist. Graduate students will find it useful for additional reading.

This collection of papers describes the evolutionary path of stars of various masses. Observational data and theoretical modeling of the stellar atmosphere and the stellar interior and their interaction are presented, covering chemical peculiarities, mass loss, and explosion, all of which are strongly related to the hydrodynamic evolution of the interior. In particular the supernova SN 1987 A is discussed for the first time in detail, including the underground neutrino observations and the detection of X-rays from the supernova. The study of its progenitor, a B 3 supergiant, was related to the topics of chemical peculiarities and mass loss mechanisms and atmospheric models. The intended readers are professional astronomers and astrophysicists, as well as physicists. The book will also be an important source of information for graduate students.

Building on its heritage in planetary science, remote sensing of the Earth's at- sphere and ionosphere with occultation methods has undergone remarkable dev- opments since the rst GPS/Met 'proof of concept' mission in 1995. Signals of Global Navigation Satellite Systems (GNSS) satellites are exploited by radio occ- tation while natural signal sources are used in solar, lunar, and stellar occultations. A range of atmospheric variables is provided reaching from fundamental atmospheric parameters such as density, pressure, and temperature to water vapor, ozone, and othertracegasspecies. Theutilityforatmosphereandclimatearisesfromtheunique properties of self-calibration, high accuracy and vertical resolution, global coverage, and (if using radio signals) all-weather capability. Occultations have become a va- able data source for atmospheric physics and chemistry, operational meteorology, climate research as well as for space weather and planetary science. The 3rd International Workshop on Occultations for Probing Atmosphere and Climate (OPAC-3) was held September 17-21, 2007, in Graz, Austria. OPAC-3 aimed at providing a casual forum and stimulating atmosphere for scienti c disc- sion, co-operation initiatives, and mutual learning and support amongst members of alldifferentoccultationcommunities. Theworkshopwasattendedby40participants from 14 different countries who actively contributed to a scienti c programme of high quality and to an excellent workshop atmosphere. The programme included 6 invited keynote presentations and 16 invited pres- tations, complemented by about 20 contributed ones including 8 posters.

How do students learn about physics without picking up a 1,000-page textbook chock-full of complicated equations? "The Physicist's World" is the answer. Here, Thomas Grissom explains clearly and succinctly what physics really is: the science of understanding how everything in the universe moves.

From the earliest efforts by Presocratic philosophers contemplating motion to the principal developments of physics through the end of the twentieth century, Grissom tells the unfolding story of our attempt to quantify the material world and to conceptualize the nature of physical laws.

Through the centuries, questions about "why" things move proved to be unanswerable in any absolute, satisfying way. Instead the question became "how" things move, a direction of thought that led to the rise of modern science. Physics emerged as a mathematical description of the motion of matter and energy, a description believed to be complete and exact, limited only by the precision of measurement. Grissom shows that in one of the great intellectual ironies, advancements in twentieth-century physics affirmed instead that this quantitative theory was capable of discovering its own limits. There is only so much that physics can reveal about the world.

This is physics for the thinking person, especially students who enjoy learning concepts, histories, and interpretations without becoming mired in complex mathematical detail. A concise survey of the field of physics, Grissom's book offers students and professionals alike a unique perspective on what physicists do, how physics is done, and how physicists view the world.

Astronomy and Astrophysics Abstracts aims to present a comprehensive documen- tation of the literature concerning all aspects of astronomy, astrophysies, and their border fields. It is devoted to the recording, summarizing, and indexing of the relevant publications throughout the world. Astronomy and Astrophysics Abstracts is prepared by a special department of the Astronomisches Rechen-Institut under the auspices of the International Astronomical Union. Volume 44 records literature published in 1987 and received before February 15, 1988. Some older documents which we received late and which are not surveyed in earlier volumes are inc1uded too. We acknowledge with thanks contributions of our colleagues all over the world. We also express our gratitude to all organiza- tions, observatories, and publishers which provide us with complimentary copies of their publications. Dr. Siegfried Bohme retired from his duties as co-editor of Astronomy and Astro- physics Abstracts on December 31, 1987. Since 1950 he partieipated in the biblio- graphie work of the institute. He served as a reviewer for the Astronomischer Jahresbericht and became one of the editors of Astronomy and Astrophysics Ab- stracts in 1969. After his retirement in 1975 he took care of, particularly, the Russian literature on a voluntary basis for 12 years. It is a pleasure to thank Siegfried Bohme for his valuable contributions. Starting with Volume 33, all the recording, correction, and data processing work was done by means of computers. The recording was done by our technical staff members Ms. Helga Ballmann, Ms. Christiane Jehn, Ms. Monika Kohl, Ms.

The high accuracy of modern astronomical spatial-temporal reference systems has made them considerably complex. This book offers a comprehensive overview of such systems. It begins with a discussion of 'The Problem of Time', including recent developments in the art of clock making (e.g., optical clocks) and various time scales. The authors address the definitions and realization of spatial coordinates by reference to remote celestial objects such as quasars. After an extensive treatment of classical equinox-based coordinates, new paradigms for setting up a celestial reference system are introduced that no longer refer to the translational and rotational motion of the Earth. The role of relativity in the definition and realization of such systems is clarified. The topics presented in this book are complemented by exercises (with solutions). The authors offer a series of files, written in Maple, a standard computer algebra system, to help readers get a feel for the various models and orders of magnitude. Beyond astrometry, the main fields of application of high-precision astronomical spatial-temporal reference systems and frames are navigation (GPS, interplanetary spacecraft navigation) and global geodynamics, which provide a high-precision Celestial Reference System and its link to any terrestrial spatial-temporal reference system. Mankind's urgent environmental questions can only be answered in the context of appropriate reference systems in which both aspects, space and time, are realized with a sufficiently high level of accuracy. This book addresses all those interested in high-precision reference systems and the various techniques (GPS, Very Long Baseline Interferometry, Satellite Laser Ranging, Lunar Laser Ranging) necessary for their realization, including the production and dissemination of time signals.

Knowledge about the outer heliosphere and the interstellar medium, which were long treated as two separate fields, has improved dramatically over the past 25 years as a consequence of recent developments: The discovery of interstellar pickup ions and neutral helium inside the heliosphere, the determination of the interstellar hydrogen distribution in the heliosphere obtained using backscattered solar Lyman-alpha radiation, the prediction and subsequent detection of the hydrogen wall just outside of the heliopause, the development of detailed global models for the interaction of solar wind plasma with the interstellar medium, and most recently, direct in-situ plasma and field measurements inside of the heliosheath. At the same time, our understanding of the nearby galactic environment, including the composition and dynamics of the warm gas clouds and hot gas in the local bubble, has benefited greatly from absorption-line spectroscopy using nearby stars as background sources and dynamic modeling. The present volume provides a synopsis of these developments organised into seven sections: Dominant physical processes in the termination shock and heliosheath, three-dimensional shape and structure of the dynamic heliosphere, relation of the plasmas and dust inside and outside of the heliosphere, origin and properties of the very local interstellar medium, energy and pressure equilibria in the local bubble, physical processes in the multiphase interstellar medium inside of the local bubble, and the roles that magnetic fields play in the outer heliosphere and the local bubble. The last theme is probably the most basic of all as magnetic fields play important roles in most of the phenomena discussed here. The volume concludes with four papers providing the "big picture" by looking at the time evolution of both the heliosphere and the local bubble, looking beyond the local bubble, and finally addressing the challenges in modeling the interface between the two media.

The concept of summerschools and workshops at the Kanzelh. ohe .. Solar Observatory,Karn ...ten,Austria,devotedtoup-to-datetopicsinsolarphysics has been proven to be extremely successful, and thus in August/September 2003 the third combined summerschool and workshop was held there. This book contains the proceedings of the Summerschool and Wo- shop "Solar Magnetic Phenomena" held from 25 August to 5 September 2003 at the Solar Observatory Kanzelh. ohe, .. which belongs to the Institute for Geophysics, Astrophysics and Meteorology of the University of Graz, Austria.

They give an overview on the following topics: observations of the pho- sphere and chromosphere, solar ?are observations and theory, coronal mass ejections and the relevance of magnetic helicity, high-energy radiation from the Sun, the physics of solar prominences and highlights from the SOHO mission. The lectures contain about 25 to 30 pages each and provide a valuableintroduction to the topics mentioned above. The comprehensive lists ofreferences at theendof each contribution enablethe interested reader to go into more detail. The second part of the book contains contributed papers. These - pers were presented anddiscussed in theworkshop sessions during the afternoons. The sessions stimulated intensive discussions between the p- ticipants and lecturers.

The book summarizes research into the fundamental properties of the outer Milky Way (including its mass, scale and rotation properties) and covers topics such as spiral structure, the interstellar medium, star formation, satellites of the Milky Way and the outer parts of some nearby galaxies. It contains new work on the outer rotation curve of the Milky Way, first results of a new low frequency galactic disk survey, new results on the scale of the Galaxy (the distance of the Sun from the center and the relation of the disk of the Milky Way to the halo). This is the first volume specifically dedicated to outer galaxy research. Professional astronomers and astrophysicists as well as graduate students will welcome this book as a guide in understanding the outer parts of the Milky Way and also other galaxies.

The 15th ESLAB symposium was held at the end of June 1981 in Amsterdam with the topic being X-ray astronomy. The aim of this symposium was to bring together the international astrophysical community in order to 1. review the present state of X-ray astronomy in the light of new observations gathered in recent missions and to review data on interesting objects in correlated wavelen8th regions; 2. discuss theoretical models describing the phenomena observed; 3. present ESA's European X-ray Observatory Satellite (EXOSAT) and to discuss future X-ray missions and their associated instrumenta tion. These topics seemed to be so interesting for the scientific community that more than 120 contributions were submitted. Of these, 94 were finally accepted and approximately 200 participants attended the 5-day meeting. The symposium was organised in nine sessions covering the whole field. Every main topic was introduced by a review lecture covering the state of-the-art. The aim of the meeting was to assess the impact of the new X-ray findings on the general astronomical knowled8e. The discussion ranged from non-degenerated stellar X-ray sources and stellar coronae tL supernovae, bursters, globular clusters, normal galaxies and finally to cosmology. In each field the philosophy was to bring together the relevant information obtained in radio, optical and X-ray observations followed by theoretical discussions. A large number of contributed papers were also presented within this framework.

In this book, the author leads the reader, step by step and without any advanced mathematics, to a clear understanding of the foundations of modern elementary particle physics and cosmology. He also addresses current and controversial questions on topics such as string theory. The book contains gentle introductions to the theories of special and general relativity, and also classical and quantum field theory. The essential aspects of these concepts are understood with the help of simple calculations; for example, the force of gravity as a consequence of the curvature of the space-time. Also treated are the Big Bang, dark matter and dark energy, as well as the presently known interactions of elementary particles: electrodynamics, the strong and the weak interactions including the Higgs boson. Finally, the book sketches as yet speculative theories: Grand Unification theories, supersymmetry, string theory and the idea of additional dimensions of space-time. Since no higher mathematical or physics expertise is required, the book is also suitable for college and university students at the beginning of their studies. Hobby astronomers and other science enthusiasts seeking a deeper insight than can be found in popular treatments will also appreciate this unique book.

Light scattering by densely packed inhomogeneous media is a particularly ch- lenging optics problem. In most cases, only approximate methods are used for the calculations. However, in the case where only a small number of macroscopic sc- tering particles are in contact (clusters or aggregates) it is possible to obtain exact results solving Maxwell's equations. Simulations are possible, however, only for a relativelysmallnumberofparticles,especiallyiftheirsizesarelargerthanthewa- length of incident light. The ?rst review chapter in PartI of this volume, prepared by Yasuhiko Okada, presents modern numerical techniques used for the simulation of optical characteristics of densely packed groups of spherical particles. In this case, Mie theory cannot provide accurate results because particles are located in the near ?eld of each other and strongly interact. As a matter of fact, Maxwell's equations must be solved not for each particle separately but for the ensemble as a whole in this case. The author describes techniques for the generation of shapes of aggregates. The orientation averaging is performed by a numerical integration with respect to Euler angles. The numerical aspects of various techniques such as the T-matrix method, discrete dipole approximation, the ?nite di?erence time domain method, e?ective medium theory, and generalized multi-particle Mie so- tion are presented. Recent advances in numerical techniques such as the grouping and adding method and also numerical orientation averaging using a Monte Carlo method are discussed in great depth.

The focus of this book is the interplay between ancient astronomy, meteorology, physics and calendrics. It looks at a set of popular instruments and texts (parapegmata) used in antiquity for astronomical weather prediction and the regulation of day-to-day life. Farmers, doctors, sailors and others needed to know when the heavens were conducive to various activities, and they developed a set of fairly sophisticated tools and texts for tracking temporal, astronomical and weather cycles. Sources are presented in full, with an accompanying translation. A comprehensive analysis explores questions such as: What methodologies were used in developing the science of astrometeorology? What kinds of instruments were employed and how did these change over time? How was the material collected and passed on? How did practices and theories differ in the different cultural contexts of Egypt, Mesopotamia, Greece and Rome?

Devised for a quantitative understanding of the physics of the universe from the solar system through the milky way to clusters of galaxies all the way to cosmology, this acclaimed text offers among the most concise and most critical ones of extant works. Special chapters are devoted to magnetic and radiation processes, disks, black-hole candidacy, bipolar flows, cosmic rays, gamma-ray bursts, image distortions, and special sources. At the same time, planet earth is viewed as the arena for life, with plants and animals having evolved to homo sapiens during cosmic time. This text is unique in covering the basic qualitative and quantitative tools, formulae as well as numbers, needed to for the precise interpretation of frontline phenomena.

The aim of this volume of scientific essays is twofold. On the one hand, by remembering the scientific figure of Eduardo R. Caianiello, it aims at focusing on his outstanding contributions - from theoretical physics to cybernetics - which after so many years still represent occasion of innovative paths to be fruitfully followed. It must be stressed the contribution that his interdisciplinary methodology can still be of great help in affording and solving present day complex problems. On the other hand, it aims at pinpointing with the help of the scientists contributing to the volume - some crucial problems in present day research in the fields of interest of Eduardo Caianiello and which are still among the main lines of investigation of some of the Institutes founded by Eduardo (Istituto di Cibernetica del CNR, IIAS, etc).

This book provides an introduction to the theory of relativity and the mathematics used in its processes. Three elements of the book make it stand apart from previously published books on the theory of relativity. First, the book starts at a lower mathematical level than standard books with tensor calculus of sufficient maturity to make it possible to give detailed calculations of relativistic predictions of practical experiments. Self-contained introductions are given, for example vector calculus, differential calculus and integrations. Second, in-between calculations have been included, making it possible for the non-technical reader to follow step-by-step calculations. Thirdly, the conceptual development is gradual and rigorous in order to provide the inexperienced reader with a philosophically satisfying understanding of the theory. The goal of this book is to provide the reader with a sound conceptual understanding of both the special and general theories of relativity, and gain an insight into how the mathematics of the theory can be utilized to calculate relativistic effects.
