This biography summarizes the seminal contributions to auroral and space science of Carl Stormer (1874 - 1957). He was the first to develop precise photographic methods to calculate heights and morphologies of diverse auroral forms during four solar cycles. Stormer independently devised numerical techniques to determine the trajectories of high-energy charged particles allowed and forbidden in the Earth's magnetic field. His theoretical analyses explained cosmic ray access to the upper atmosphere, 20 years before they were identified by other scientists. Stormer's crowning achievement, "The Polar Aurora," published when he was 81 years old, stands to this day as a regularly cited guide in graduate-level courses on space physics. The authors present the life of this prodigious scientist in relation to the cultural life of early 20th century in Norway and to the development of the space sciences in the post-Sputnik era.
In this book an international group of specialists discusses studies of exoplanets subjected to extreme stellar radiation and plasma conditions. It is shown that such studies will help us to understand how terrestrial planets and their atmospheres, including the early Venus, Earth and Mars, evolved during the host star's active early phase. The book presents an analysis of findings from Hubble Space Telescope observations of transiting exoplanets, as well as applications of advanced numerical models for characterizing the upper atmosphere structure and stellar environments of exoplanets. The authors also address detections of atoms and molecules in the atmosphere of "hot Jupiters" by NASA's Spitzer telescope. The observational and theoretical investigations and discoveries presented are both timely and important in the context of the next generation of space telescopes. The book is divided into four main parts, grouping chapters on exoplanet host star radiation and plasma environments, exoplanet upper atmosphere and environment observations, exoplanet and stellar magnetospheres, and exoplanet observation and characterization. The book closes with an outlook on the future of this research field.
This book presents lecture materials from the Third LOFAR Data School, transformed into a coherent and complete reference book describing the LOFAR design, along with descriptions of primary science cases, data processing techniques, and recipes for data handling. Together with hands-on exercises the chapters, based on the lecture notes, teach fundamentals and practical knowledge. LOFAR is a new and innovative radio telescope operating at low radio frequencies (10-250 MHz) and is the first of a new generation of radio interferometers that are leading the way to the ambitious Square Kilometre Array (SKA) to be built in the next decade. This unique reference guide serves as a primary information source for research groups around the world that seek to make the most of LOFAR data, as well as those who will push these topics forward to the next level with the design, construction, and realization of the SKA. This book will also be useful as supplementary reading material for any astrophysics overview or astrophysical techniques course, particularly those geared towards radio astronomy (and radio astronomy techniques).
After the huge national and international success of 'Longitude' and 'Gallileo's Daughter', Dava Sobel tells the human story of the nine planets of our solar system. This groundbreaking new work traces the 'lives' of each member of our solar family, from myth and history, astrology and science fiction, to the latest data from the modern era's robotic space probes. Whether revealing what hides behind Venus's cocoon of acid clouds, describing Neptune's complex beauty, or capturing first-hand the excitement at the Jet Propulsion Laboratory when the first pictures from Cassini at Saturn were recently beamed to earth, Dava Sobel's unique tour of the solar system is filled with fascination and beauty. In lyrical prose interspersed with poems by Tennyson, Blake and others, 'The Planets' gives a breathtaking, intimate view of those heavenly bodies that have captured the imagination since humanity's first glimpse of the glittering night skies. Timely and timeless, 'The Planets' will engage and delight as it unravels the mysteries of the cosmos. It is of infinite relevance to this age in which new planets are being discovered elsewhere in our galaxy.
The Pacific Rim Conferences for the first decade from the mid 1980's to the mid 1990's were primary concerned with binary stars research. The Conference expanded to all areas of Stellar Astrophysics for the last two meetings in Hong Kong; at Hong Kong University of Science and Technology in 1997 and at the Hong Kong University in 1999. At the conclusion of the very successful Pacific Rim Conference on Stellar Astrophysics held in Hong Kong University, members of the Sci entific Organizing Committee began planning for the next conference. We approached Professor Tan Lu of Nanjing University and Professor Tipei Li of the Institute of High Energy Physics about hosting a con ference in China. The city of Xi'an in Shaanxi province and a city in Yunnan province, were considered to be the most likely locations. It be came crucial to find the right person to serve as Chair (or Co-chairs) for the Local Organizing Committee. Initially, Professor Lu was the logical choice but he declined for personal reasons. Professor Li was invited to lead a new department of Astrophysics at Tsinghua University so he could not take on the additional load of chairing the LOC. Professor Gang Zhao of Beijing Astronomical Observatory was approached to take on the task but he also declined. This has been a busy time for Chinese astronomers. The SOC decided to have the conference dedicated to honor Dr. Helmut A."
Every year Earth is bombarded with about 40,000 tons of extraterrestrial material. This includes microscopic cosmic dust particles shed by comets and asteroids in outer space, meteorites, as well as large comets and asteroids that have led to catastrophic events in the geologic past. Originally considered only a curiosity, extraterrestrial matter found on Earth provides the only samples we have from comets, asteroids and other planets. Only recently mankind has started to actively collect extraterrestrial matter in space (Apollo program, Stardust mission) rather than to wait for its delivery to Earth. Still, most of our knowledge of the origin and evolution of our solar system is based on careful studies of meteorites, cosmic dust, and traces of large impact events in the geologic record such as the mass extinction that terminated the Cretaceous Period and led to the extinction of the dinosaurs. This book summarizes our current knowledge of the properties, origin, orbital evolution and accretion mechanism of extraterrestrial matter accreted on Earth and sheds light on accretion processes and fluxes in the geologic past. The chapters in the first part of the book are arranged in order to follow extraterrestrial matter from its origin in space, its orbital evolution on its way to Earth, its interaction with the Earth magnetosphere and atmosphere to its more or less violent collision with the Earth's surface. In the second part of the book several chapters deal with the present?day flux of cosmic dust and meteorites to Earth. Finally, several chapters deal with the reconstruction of the accretion history of extraterrestrial matter on Earth, starting with the most recent geologic past and ending with the very early, violent accretion period shortly after the formation of Earth, Moon and other solid planets in our solar system.
This book collects extended and specialized reviews on topics linking astrophysics and particle physics at a level intermediate between a graduate student and a young researcher. The book includes also three reviews on observational techniques used in forefront astrophysics and short articles on research performed in Latin America. The reviews, updated and written by specialized researchers, describe the state of the art in the related research topics. This book is a valuable complement not only for research but also for lecturers in specialized course of high energy astrophysics, cosmic ray astrophysics and particle physics."
For every galaxy in the field or in clusters, there are about three galaxies in groups. The Milky Way itself resides in a group. Groups in the local universe offer the chance to study galaxies in environments characterized by strong interactions. In the cosmological context, groups trace large-scale structures better than clusters; the evolution of groups and clusters appears to be related. All these aspects of research are summarized in this book.
Over the centuries the starry night sky has inspired poets and
scientists alike, and though the fruits of these inspirations take
very different forms, they often enrich each other. Acclaimed
science writer David Levy, the codiscoverer of Comet Shoemaker-Levy
9, has written this wonderful jewel of a book to celebrate the
complementary visions of human wonder and curiosity that are
expressed in the separate disciplines of poetry and astronomy.
1st edition: Winner of the 2004 IAA Life Sciences Book Award! This 2nd Edition represents a complete revision with about 23% more pages and new material compared to the first edition; it includes several recent studies involving astronauts and cosmonauts; and discusses the new field of space tourism. It deals with psychological, psychiatric, and psychosocial issues that affect people who live and work in space. Unlike other books that focus on anecdotal reports and ground-based simulation studies, this book emphasizes the findings from psychological research conducted during actual space missions. Both authors have been active in such research. What is presented in this readable text has previously been found only in scientific journal articles. Topics that are discussed include: behavioral adaptation to space; human performance and cognitive effects; crewmember interactions; psychiatric responses; psychological countermeasures related to habitability factors, work-design, selection, training, and in-flight monitoring and support; and the impact of expeditionary missions to Mars and beyond. People finding this book of interest will include psychology and social science students and professors in universities, medical students and residents in psychiatry and aerospace medicine, human factors workers in space and aviation professions, individuals involved with isolated environments on Earth (e.g., the Antarctic, submarines), aerospace workers in businesses and space agencies such as NASA and ESA, and anyone who is interested in learning the facts about the human side of long-duration space missions. 1st edition reviews: a ~Drs. Kanas and Manzey have produced acomprehensive review of the issues and research in the areas of space psychology and psychiatry. This includes a long overdue up-to-date compilation of findings from research performed in space as well as anecdotal reports. The authors' personal involvement and experience in space research and operations shows throughout the book in its presentation and research of the issues as well as in the insights offered. Highly informative, well organized and written at a level appropriate for a broad range of readers, this book will be a reference source for space professionals, researchers, students, and interested laymen alike. a ~ Leena Tomi, Deputy Director, Operational Space Medicine,
Canadian Space Agency 'An excellent book by two outstanding experts. The refreshing mix between review and original research results spiced with personal experiences makes it interesting for every reader.' Oliver Angerer, M.D., Human Exploration Science Coordinator, European Space Agency "This book is not just a record of what can go wrong with regard to mental health and performance, but explores a number of prudent psychological, ergonomic, and design engineering countermeasures to help guide future mission planners and spacecraft engineers[a ]]Written in a clear and engaging style, this book will not only interest the general space enthusiast, but all human factors specialists and anyone else studying the human reaction to extreme and unusual environments. As a comprehensive account of what we have learned so far about the psychological challenges of space travel, Space Psychology andPsychiatry should also be on the bookshelf of any researcher plotting the future course of human spaceflight."

In Shakespeare and the Dawn of Modern Science, renowned astronomy expert Peter Usher expands upon his allegorical interpretation of Hamlet and analyzes four more plays, Love's Labour's Lost, Cymbeline, The Merchant of Venice, and The Winter's Tale. With painstaking thoroughness, he dissects the plays and reveals that, contrary to current belief, Shakespeare was well aware of the scientific revolutions of his time. Moreover, Shakespeare imbeds in the allegorical subtext information on the appearances of the Sun, Moon, planets, and stars that he could not have known without telescopic aid, yet these plays appeared coeval with or prior to the commonly accepted date of 1610 for the invention and first use of the astronomical telescope. Dr. Usher argues that an early telescope, the so-called perspective glass, was the likely means for the acquisition of these data. This device was invented by the mathematician Leonard Digges, whose grandson of the same name contributed poems to the First and Second Folio editions of Shakespeare's plays. Shakespeare and the Dawn of Modern Science is an important addition to literature, history, and science collections as well as to personal libraries.
This book provides an up-to-date understanding of the progress and current problems of the interplay of nonlocality in the classical theories of gravitation and quantum theory. These problems lie on the border between general relativity and quantum physics, including quantum gravity.
In this PhD thesis, which was nominated for publication in this series by the Astronomical Institute at Charles University, Prague, the author investigates the orbital evolution of an initially thin stellar disc around a supermassive black hole, considering various perturbative sources of gravity. His findings, obtained by both direct numerical N-body modelling and using standard perturbation methods, offer a viable theoretical explanation for the observed configuration of young stars in the Galactic Centre. This marks a significant contribution to a topic of great interest in contemporary astrophysics. The author also shows in his thesis that a secular instability (m = 1 mode) may occur in the embedding spherical cluster of old stars. This increases the richness of possible evolution scenarios of the embedding cluster and may lead to effective feeding of supermassive black holes through tidal disruption of stars on extremely eccentric orbits.
The discovery of chemical elements in celestial bodies and the first estimates of the chemical composition of the solar atmosphere were early results of Astrophysics - the subdiscipline of Astronomy that was originally concerned with the general laws of radiation and with spectroscopy. Following the initial quantitative abundance studies by Henry Norris Russell and by Cecilia Payne-Gaposchkin, a tremendous amount of theoretical, observa tional, laboratory and computational work led to a steadily improving body of knowledge of photospheric abundances - a body of knowledge that served to guide the theory of stellar evolution. Solar abundances determined from photospheric spectra, together with the very similar abundances determined from carbonaceous chondrites (where extensive information on isotopic composition is available as well), are nowadays the reference for all cosmic composition measures. Early astrophysical studies of the solar photospheric composition made use of atmosphere models and atomic data. Consistent abundances derived from different atmospheric layers and from lines of different strength helped to confirm and estab lish both models and atomic data, and eventually led to the now accepted, so-called "absolute" abundance values - which, for practical reasons, however, are usually given relative to the number of hydrogen nuclei.

A decade after the confirmation of the Kuiper Belt's existence, 80
of the world's experts gathered in Chile to review what has been
learned since 1992. This record of the meeting is enhanced by
several specially solicited papers covering additional material not
presented at the conference. The volume includes papers on the
dynamics of the trans-Neptunian region, the results of deep surveys
for the new objects and the evidence for an outer Edge to the
Edgeworth-Kuiper belt. Physical observations of many objects are
described and attempts are made to bring these data into some
coherent picture of the distant solar system. The interior physics
of these distant, icy objects, and the link between the Kuiper Belt
and dust disks around other stars are also considered. Of
particular interest is a set of papers on how the surfaces of
distant asteroids are affected by various types of radiation, an
area crucial to the interpretation of data being collected by large
ground based telescopes.
This book contains an up-to-date review of the structure and evolution of disk galaxies from both the observational and theoretical point of view. The book is the proceedings of the Island Universes conference held at the island of Terschelling, The Netherlands in July 2005, which attracted about 130 experts and students in the field. The conference was organized as a tribute to Dr. Piet C. van der Kruit for receiving the honorary Jacobus C. Kapteyn Professorship in Astronomy. The eight topical themes discussed at the meeting are reflected in these proceedings: 1) Properties of Stellar Disks, 2) Kinematics and Dynamics of Disk Galaxies, 3) Bars, Spiral Structure, and Secular Evolution in Disk Galaxies, 4) The Outskirts and Environment of Disk Galaxies, 5) Interstellar Matter, 6) (Evolution of) Star Formation in Galactic Disks, 7) Disk Galaxies through Cosmic Time, and 8) Formation Models of Disk Galaxies.
What is time? What do we understand when we think about time? What do we mean by ‘now’? This book covers concisely all the different aspects of time with an anchoring point within the geological sciences. Here successions of strata are seen as representing successions of events in the long history of the earth; palaeontology provides a record of organic evolution through nearly the whole of these several thousand million years. The rest of the book diversifies in discussing the measurement of time both physically and biologically; our human perception of it; the ending of personal time in death; the pervading presence of time in the arts; out through astronomy to cosmology; into philosophy and religion. The idea of time is a very complex one but this book undertakes a journey to prove that it is not beyond comprehension.
This survey will surpass its namesake, Gods, Graves and Scholars by Ceram, just as the Stars preceded the Gods and the Stones preceded the Graves.
Galaxy groups and clusters provide excellent laboratories for studying galaxy properties in different environments and at different look-back times. In particular, the recent detections of high-redshift cluster candidates, only possible with the current high-technology instrumentation, add a new dimension to the problem. Along with the ever increasing computing power and sophisticated algorithms to model clusters of galaxies, it may help us to understand the origins of today's groups and clusters, as well as of their member galaxies. These workshop proceedings provide a snapshot of the current research in this subject, covering the observations, theory and numerical simulations relevant to galaxy evolution in groups and clusters. In this book, intended primarily to researchers in the field, particular emphasis is given to the recent impressive progress in the field, on important new results, and on the future prospects and open questions to be tackled.
The articles included in this Volume represent a broad and
highly qualified view on the present state of general relativity,
quantum gravity, and their cosmological and astrophysical
implications. As such, it may serve as a valuable source of
knowledge and inspiration for experts in these fields, as well as
an advanced source of information for young researchers.
A contemporary of Galileo and a forerunner of Isaac Newton, Johannes Kepler (1571-1630) was a pioneering German scientist and a pivotal figure in the history of astronomy. This colorful, well-researched biography brings the man and his scientific discoveries to life, showing how his contributions were every bit as important as those of Copernicus, Galileo, and Newton.It was Kepler who first advocated the completely new concept of a physical force emanating from the sun that controls the motion of the planets--today we call this gravity and take it for granted. He also established that the orbits of the planets were elliptical in shape and not circular. And his three laws of planetary motion are still used by contemporary astronomers and space scientists.The author focuses not just on these and other momentous breakthroughs but also on Kepler's arduous life, punctuated by frequent tragedy and hardships. His first wife died young, and eight of the twelve children he fathered succumbed to disease in infancy or childhood. He was frequently caught up in the religious persecutions of the day. His mother narrowly escaped death when she was accused of being a witch.Intermingling historical and personal details of Kepler's life with lucid explanations of his scientific research, this book presents a sympathetic portrait of the man and underscores the critical importance of Kepler's discoveries in the history of astronomy.
