Solar Flare Magnetic Fields and Plasmas (Paperback, 2012 ed.): Yuhong Fan, George Fisher Solar Flare Magnetic Fields and Plasmas (Paperback, 2012 ed.)
Yuhong Fan, George Fisher
R2,765 Discovery Miles 27 650 Ships in 10 - 15 working days

This volume is devoted to the dynamics and diagnostics of solar magnetic fields and plasmas in the Sun's atmosphere. Five broad areas of current research in Solar Physics are presented: (1) New techniques for incorporating radiation transfer effects into three-dimensional magnetohydrodynamic models of the solar interior and atmosphere, (2) The connection between observed radiation processes occurring during flares and the underlying flare energy release and transport mechanisms, (3) The global balance of forces and momenta that occur during flares, (4) The data-analysis and theoretical tools needed to understand and assimilate vector magnetogram observations and (5) Connecting flare and CME phenomena to the topological properties of the magnetic field in the Solar Atmosphere. The role of the Sun's magnetic field is a major emphasis of this book, which was inspired by a workshop honoring Richard C. (Dick) Canfield. Dick has been making profound contributions to these areas of research over a long and productive scientific career. Many of the articles in this topical issue were first presented as talks during this workshop and represent substantial original work. The workshop was held 9 - 11 August 2010, at the Center Green campus of the National Center for Atmospheric Research (NCAR) in Boulder, Colorado. This volume is aimed at researchers and graduate students active in solar physics, solar-terrestrial physics and magneto-hydrodynamics. Previously published in Solar Physics journal, Vol. 277/1, 2012.

R4,991 Discovery Miles 49 910 Ships in 10 - 15 working days

Cosmogenic radionuclides are radioactive isotopes which are produced by natural processes and distributed within the Earth system. With a holistic view of the environment the authors show in this book how cosmogenic radionuclides can be used to trace and to reconstruct the history of a large variety of processes. They discuss the way in which cosmogenic radionuclides can assist in the quantification of complex processes in the present-day environment. The book aims to demonstrate to the reader the strength of analytic tools based on cosmogenic radionuclides, their contribution to almost any field of modern science, and how these tools may assist in the solution of many present and future problems that we face here on Earth. The book provides a comprehensive discussion of the basic principles behind the applications of cosmogenic (and other) radionuclides as environmental tracers and dating tools. The second section of the book discusses in some detail the production of radionuclides by cosmic radiation, their transport and distribution in the atmosphere and the hydrosphere, their storage in natural archives, and how they are measured. The third section of the book presents a number of examples selected to illustrate typical tracer and dating applications in a number of different spheres (atmosphere, hydrosphere, geosphere, biosphere, solar physics and astronomy). At the same time the authors have outlined the limitations of the use of cosmogenic radionuclides. Written on a level understandable by graduate students without specialist skills in physics or mathematics, the book addresses a wide audience, ranging from archaeology, biophysics, and geophysics, to atmospheric physics, hydrology, astrophysics and space science.

The first Catalogue of Meteorites from South America includes new specimens never previously reported, while doubtful cases and pseudometeorites have been deliberately omitted.

The falling of these objects is a random event, but the sites where old meteorites are found tend to be focused in certain areas, e.g. in the deflation surfaces in Chile s Atacama Desert, due to favorable climate conditions and ablation processes.

Our Catalogue provides basic information on each specimen like its provenance and the place where it was discovered (in geographic co-ordinates and with illustrative maps), its official name, its classification type (class, and if applicable, weathering grade and shock stage), if it was seen falling or was found by chance, its total mass or weight, the institution where it is held, and the most important bibliographic references about it.

These proceedings bring together ideas from solar and stellar physics. The sun is near enough for rather detailed observations and one chapter is devoted to the more recent experimental data from observations from space. On the other hand the multitude of stars provides a wide range of physical parameters to test hypotheses in solar and stellar astrophysics. The reader will find an illuminating overview of these fields ranging from the dynamo in the convection zone to the stellar envelopes and winds in the outer regions. In particular the importance of small-scale magnetohydrodynamic processes for the activity phenomena plays an important role in the contributions to this volume. For both students and researchers the general introduction by N. O. Weiss makes an excellent guide to this very active field of research. (See also Lecture Notes in Physics Vol. 291.)

R1,455 Discovery Miles 14 550 Ships in 10 - 15 working days

This volume provides an overview of our current understanding of the physics related to: coronal structures and coronal heating; large-scale coronal shock waves and coronal mass ejections; particle beams in the solar corona and in the interplanetary medium; and explosive energy-release phenomena and particle acceleration. The different articles give a well-balanced presentation of relevant observations based upon various techniques, models and theories, providing a global view of these phenomena and of the underlying physics. In-situ measurements of particles and waves with ULYSSES and WIND and spectral and imaging data from SOHO and YOHKOH provide an unprecedented richness of relevant data. For their better understanding, radio observations - also included in this book - play a key role.

This volume brings together theoretical ideas on the plasma physics of both hot and dense plasmas in the solar atmosphere and similar physics applied to the tenuous and cooler plasmas found in the heliosphere. It is complemented by recent observations. Helioseismology covers the solar interior and the neutrino problem. Solar and stellar activity cycles are addressed. The dynamics of magnetic flux tubes in the solar atmosphere and material flows through the chromosphere into the upper atmosphere are comprehensively reviewed. Energy release processes and the production of energetic particles are important to understanding events in the solar atmosphere and to the dynamics of the tenuous heliosphere. A glimpse of the future is offered by concluding chapters on new ground-based and space instrumentation.

Fernando Haas
R2,767 Discovery Miles 27 670 Ships in 10 - 15 working days

This book provides an overview of the basic concepts and new methods in the emerging scientific area known as quantum plasmas. In the near future, quantum effects in plasmas will be unavoidable, particularly in high density scenarios such as those in the next-generation intense laser-solid density plasma experiment or in compact astrophysics objects. Currently, plasmas are in the forefront of many intriguing questions around the transition from microscopic to macroscopic modeling of charged particle systems. Quantum Plasmas: an Hydrodynamic Approach is devoted to the quantum hydrodynamic model paradigm, which, unlike straight quantum kinetic theory, is much more amenable to investigate the nonlinear realm of quantum plasmas. The reader will have a step-by-step construction of the quantum hydrodynamic method applied to plasmas. The book is intended for specialists in classical plasma physics interested in methods of quantum plasma theory, as well as scientists interested in common aspects of two major areas of knowledge: plasma and quantum theory. In these chapters, the quantum hydrodynamic model for plasmas, which has continuously evolved over the past decade, will be summarized to include both the development and applications of the method.

Duncan Lunan
R2,495 Discovery Miles 24 950 Ships in 10 - 15 working days

Incoming Asteroid is based on a project within ASTRA (the Association in Scotland to Research into Astronautics) to provide scientific answers to the question what would we do if we knew there was going to be an asteroid impact in ten years time or less?
Clearly there are many things humanity can do nothing about, for example an unseen object traveling towards us so fast that we have no time to prepare, or an object so large it may be unstoppable. A realistic hazard model was decided upon, and the scenario developed from that: an incoming object about 1 kilometer in diameter, in an orbit ranging from the outer rim of the Asteroid Belt to within that of Earth s.
Three basic possibilities are considered in this book. The first is the deflection of the asteroid, using remote probes along with a number of possible technologies to change the asteroid s course. Second is the attempt of a manned mission, in order to plant a propulsion system on the asteroid to push it into a different orbit. Third is the nuclear option, a last-ditch attempt to break up and then disperse the asteroid using nuclear weapons. (A rather impractical combination of these second and third options were used as the plot of the popular 1998 Bruce Willis feature film, Armageddon.)
Although the cost of developing the technology needed to protect the Earth would be substantial, there would certainly be spin-off benefits. These could eventually result in practical small-scale atomic energy sources, new propulsion systems that could make extraterrestrial mining within the solar system a possibility, and other as-yet unforeseen benefits.

And finally, Incoming Asteroid considers the political implications - how governments across the world should best react to the threat with a view to minimizing loss of life, and in the weeks running up to the possible impact, preventing panic in the population."

R1,537 Discovery Miles 15 370 Ships in 10 - 15 working days

Since the launch of UoSat-1 of the University of Surrey (United Kingdom) in 1981, small satellites proved regularly to be useful, beneficial, and cost-effective tools. Typical tasks cover education and workforce development, technology demonstration, verification and validation, scientific and engineering research as well as commercial applications. Today the launch masses range over almost three orders of magnitude starting at less than a kilogram up to a few hundred kilograms, with budgets of less than US$ 100.00 and up to millions within very short timeframes of sometimes less than two years. Therefore each category of small satellites provides specific challenges in design, development and operations. Small satellites offer great potentials to gain responsive, low-cost access to space within a short timeframe for institutions, companies, regions and countries beyond the traditional big players in the space arena. For these reasons (particularly the low cost of construction, launch and operation), small (micro, cube or nano) satellites are being preferred by students and educational institutions, amateur radio operators, small and developing countries, international aid agencies and most recently by defense agencies and satellite operators who are examining deployment of constellation clusters instead of conventional application satellites. In some cases these new capabilities are being deployed as hosted payloads on larger satellites. The advent of hosted payloads as a significant part of the satellite industry represents a key new topic that this book will address. The number of small satellites-of various types--is increasing fast as their benefits are being realized. This short and unique interdisciplinary book, covering both technical and regulatory aspects, examines all the different types of applications and reasons for small as well as exploring technical and operational innovations that are being introduced. It also examines the new technical standards, removal techniques or other methods that might help to address current problems and the regulatory issues and procedures to ameliorate problems associated with small satellites, especially mounting levels of orbital debris and noncompliance with radio frequency and national licensing requirements, liabilities, export controls and so on.

It has been nearly 100 years since the Apollo moon landings, when Jack and Vladimir, two astronauts on a mission to Venus, discover a mysterious void related to indigenous life on the planet. Subsequently more voids are detected on Earth, Mars, Titan, and, quite ominously, inside a planetoid emerging from the Kuiper belt.

Jack is sent to investigate the voids in the Solar System and intercept the planetoid - which, as becomes increasingly clear, is inhabited by alien life forms. Jack and his crew will have little time to understand their alien biochemistry, abilities, behavior patterns, resilience, and technology, but also how these life forms relate to the voids.

Humankind's first encounter with these exotic life forms couldn't be more fateful, becoming a race against time to save life on Earth and to reveal the true nature of the voids, which seem to be intrinsically related to life and the universe itself. In this novel, the author combines many topics related to state-of-the-art research in the field of astrobiology with fictional elements to produce a thrilling page turner.

This new version significantly develops the astrobiological denouement of the plot and features an extensive non-technical appendix where the underlying science is presented and discussed.

From the reviews of the first edition ("Voids of Eternity: Alien Encounter")

Here's a thrilling yarn in the best "hard SF" tradition of Asimov, James Hogan, and Ben Bova, written by a scientist who knows all about the possibilities of life in the solar system and beyond. Dirk Schulze-Makuch weaves into his book all the astrobiological themes he's worked on in recent years -- speculation about creatures in the atmosphere of Venus and on and under the surface of Mars and Titan -- together with some well-informed Eastern philosophy and a cracking good space battle. A great first novel from a rising talent. Highly recommended. David Darling, on amazon.com, 2009The research interests of Dr. Schulze-Makuch, currently a professor at Washington State University, focus on evolutionary adaptation strategies of organisms in their natural environment, particularly extreme environments such as found on other planetary bodies. Dirk Schulze-Makuch is best known for his publications on extraterrestrial life, being coauthor of three books on the topic: "We Are Not Alone: Why We Have Already Found Extraterrestrial Life" (2010), "Cosmic Biology: How Life could Evolve on Other Worlds" (2010), and "Life in the Universe: Expectations and Constraints" (2004). In 2011 he published with Paul Davies "A One Way Mission to Mars: Colonizing the Red Planet" and in 2012 with David Darling "Megacatastrophes Nine Strange Ways the World Could End."

The Workshop on Tunable Solid State Lasers for Remote Sensing was held at Stanford University in October 1984 to assess the state of the art in tunable solid state lasers for remote sensing from satellite platforms. The value of conducting global remote sensing measurements of atmospheric chemistry, climate, and weather in the 1990s is now established. What is not yet defined, however, is the status of the developing tunable laser technology that must meet both the scientific requirements and the space platform constraints. This workshop was convened by the Office of Aeronautics and Space Technology (OAST) of the National Aeronautics and Space Administration (NASA) to assess the status and progress in tunable solid state laser sources for remote sensing. The workshop was organized to facilitate information exchange across a number of technologies from remote sensing requirements to crystal growth of the materials important for the development of the tunable laser sources. The emphasis was on the recent developments in tunable solid state laser sources necessary to meet the future transmitter requirements for global remote sensing. A goal of the workshop was to form recommendations to NASA on the current and future prospects for solid state laser technology that will allow remote sensing measurements from air, shuttle, and free-flying satellite platforms. The emphasis was on solid state laser sources because they offer the best potential for meeting the demanding requirements of compact size, good efficiency, and long operational lifetimes required for future space station and free-flying platform operation.

R1,817 Discovery Miles 18 170 Ships in 10 - 15 working days

Space weather has attracted a lot of attention in recent times. Severe space weather can disrupt spacecraft, and on Earth can be the cause of power outages and power station failure. It also presents a radiation hazard for airline passengers and astronauts. These "magnetic storms" are most commonly caused by coronal mass ejections, or CMES, which are large eruptions of plasma and magnetic field from the Sun that can reach speeds of several thousand km/s. In this SpringerBrief, Space Weather and Coronal Mass Ejections, author Timothy Howard briefly introduces the coronal mass ejection, its scientific importance, and its relevance to space weather at Earth and other planets. This title focuses on the latest advances in CME observation and modeling, including new results from the NASA STEREO and SDO missions. It also includes topical issues regarding space weather and the most recent observations and anecdotal examples of the impacts of space weather and CMEs.

We stayed with the tried and tested EUROTRAC format, giving ample time for poster sessions as well as side meetings and workshops. The invited talks, over 35 in all, contributed breadth and depth. The Symposium had the focal points of "Shaping the Future" and "Scientiftc Research and Environmental Policy". The "Highlights from the Subprojects" were well represented by a series of talks and of course by the ca 300 posters. Guest poster contributions added to the spectrum of scientiftc coverage. An innovation for 2000 is the publication of these Proceedings in a book containing the extended abstracts of the lectures and a companion CD-ROM with the extended abstracts of the posters as well as the lectures. The availability of the Proceedings on a CD will enable us to distribute them more widely.
