Lectures in Magnetohydrodynamics: With an Appendix on Extended MHD

Lectures in Magnetohydrodynamics: With an Appendix on Extended MHD by Dalton D. Schnack
English | PDF (True) | 2009 | 317 Pages | ISBN : 3642006876 | 5.5 MB

Magnetohydrodynamics, or MHD, is a theoretical way of describing the statics and dynamics of electrically conducting uids. The most important of these uids occurring in both nature and the laboratory are ionized gases, called plasmas. These have the simultaneous properties of conducting electricity and being electrically charge neutral on almost all length scales. The study of these gases is called plasma physics. MHD is the poor cousin of plasma physics. It is the simplest theory of plasma dynamics. In most introductory courses, it is usually afforded a short chapter or lecture at most: Alfven ´ waves, the kink mode, and that is it. (Now, on to Landau damping!) In advanced plasma courses, such as those dealing with waves or kinetic theory, it is given an even more cursory treatment, a brief mention on the way to things more profound and interesting. (It is just MHD! Besides, real plasma phy- cists do kinetic theory!) Nonetheless, MHD is an indispensable tool in all applications of plasma physics.

Space Physics: An Introduction to Plasmas and Particles in the Heliosphere and Magnetospheres by May-Britt Kallenrode
English | PDF | 2004 | 487 Pages | ISBN : 3540206175 | 50 MB

Space is a large natural plasma laboratory offering a wealth of phenomena which range from the simple to the highly complex and non-linear. This book begins with an introduction to basic principles such as single-particle motion, magnetohydrodynamics and plasma waves. It incorporates these concepts into an analysis of complex phenomena including the sun and solar activity, shocks, interplanetary space and magnetospheres, and finally the interaction between these entities in solar-terrestrial relationships. In all these subfields of space research, special attention is paid to energetic particles. The book concludes with a brief chapter on instrumentation. In this third edition, numerous examples have been added to illustrate the basic concepts and aid the reader in applying such concepts to real world physics. In addition, recent observations (ACE, TRACE, Wind) have been included. The chapter on solar-terrestrial relationships has been expanded to introduce the current research topic of Space Weather.

Cosmic Ray Interactions, Propagation, and Acceleration in Space Plasmas by Lev I. Dorman
English | PDF (True) | 2006 | 877 Pages | ISBN : 140205100X | 14.9 MB

xxii CONTENTS In 1957 I was invited to work on special problems in Magnetic Laboratory of the Academy of Sciences of USSR as a Head of Department of Magnetic Hydrodynamics. In few years this Laboratory was transfered into the I. V. Kurchatov Institute of Atomic Energy, and I continued to work in this Institute up to 1965. In parallel I also worked at Moscow State University as Professor in the CR and Space Research Team. I also gave lectures in Irkutsk, Alma-Ata, Nalchik, Tbilisi, Erevan, Samarkand, and others places. Over about 40 years of teaching under my supervision more than hundred graduate students and scientists in USSR and some other countries gained their Ph. D. and several tenths became Doctors of Science. As my hobby I continued to work in CR research, and as Vice-President of All-Union Section of Cosmic Rays and Radiation Belts, took an active part in preparing the Soviet net of CR stations to the IGY (International Geophysical Year, 1957-1958): we equipped all soviet stations in USSR and in Antarctica with standard cubic and semi-cubic muon telescopes and with neutron monitors of IGY (or Simpson’s) type. In connection with preparing for the IQSY (the International Quiet Sun Year, 1964-1965), the soviet net of CR stations was extended about two fold and they were equipped with neutron super-monitors of IQSY type (with an effective surface about 10 times bigger than the previous monitor of IGY type).

Space Plasma Simulation

Space Plasma Simulation by Jörg Büchner, Manfred Scholer, Christian T. Dum
English | PDF | 2003 | 363 Pages | ISBN : 3540006982 | 8.7 MB

The aim of this book is twofold: to provide an introduction for newcomers to state of the art computer simulation techniques in space plasma physics and an overview of current developments. Computer simulation has reached a stage where it can be a highly useful tool for guiding theory and for making predictions of space plasma phenomena, ranging from microscopic to global scales. The various articles are arranged, as much as possible, according to the - derlying simulation technique, starting with the technique that makes the least number of assumptions: a fully kinetic approach which solves the coupled set of Maxwell’s equations for the electromagnetic ?eld and the equations of motion for a very large number of charged particles (electrons and ions) in this ?eld. Clearly, this is also the computationally most demanding model. Therefore, even with present day high performance computers, it is the most restrictive in terms of the space and time domain and the range of particle parameters that can be covered by the simulation experiments. It still makes sense, therefore, to also use models, which due to their simp- fying assumptions, seem less realistic, although the e?ect of these assumptions on the outcome of the simulation experiments needs to be carefully assessed.

Space Plasma Physics: Stationary Processes

Space Plasma Physics: Stationary Processes by Akira Hasegawa , Tetsuya Sato
English | PDF | 1989 | 183 Pages | ISBN : 3642741878 | 20.1 MB

During the 30 years of space exploration, important discoveries in the near-earth environment such as the Van Allen belts, the plasmapause, the magnetotail and the bow shock, to name a few, have been made. Coupling between the solar wind and the magnetosphere and energy transfer processes between them are being identified. Space physics is clearly approaching a new era, where the emphasis is being shifted from discoveries to understanding. One way of identifying the new direction may be found in the recent contribution of atmospheric science and oceanography to the development of fluid dynamics. Hydrodynamics is a branch of classical physics in which important discoveries have been made in the era of Rayleigh, Taylor, Kelvin and Helmholtz. However, recent progress in global measurements using man-made satellites and in large scale computer simulations carried out by scientists in the fields of atmospheric science and oceanography have created new activities in hydrodynamics and produced important new discoveries, such as chaos and strange attractors, localized nonlinear vortices and solitons. As space physics approaches the new era, there should be no reason why space scientists cannot contribute, in a similar manner, to fundamental discoveries in plasma physics in the course of understanding dynamical processes in space plasmas.

Even today flying into space is an undertaking at the borderline of what is curreiitly feasible. h veq complex assen~bly of sophist~icated machinery is needed in order to reach orbit and return from there to Eart,ll safely. A11 ast,ronaut knows that only if t,he rocket engines, inertial navigat,ion platforms. hydraulic systems; generators of electrical power, att,itude control systems, life support sj stems, coinput~ers. data transmission equipment, heat shields and many other components work flawlessly can he or she accomplish a mission in good llealt,h. I11 other words there is risk, but the odds are better than even. How else could a man or a woman see the incredible beauty of our planet Earth from a clist,ance? Take t,he combination of it,s colours. white and blue. It is so breatht,akingly stunning, that most likely not even a poet could find words to adequately describe it. There is the curved line of the horizon with an incredibly black slij above it. L4t first sight it is evident how elidless and empty the universe actually is. The Eart,h's horizon is fringed with a royal blue seam, our at,mosphere. Its beauty and fragility are thrilling, and seen from orbit it is instantly apparent that there is not much air around us.

Astrobiology: The Quest for the Conditions of Life

Astrobiology: The Quest for the Conditions of Life by Gerda Horneck, Christa Baumstark-Khan
English | PDF | 2002 | 415 Pages | ISBN : 3642639577 | 57.6 MB

How did life originate in the universe? How did it all start after the creation of matter and the formation of elements in the stars? What are the pathways from the first organic molecules in space to the evolution of complex life forms on Earth and perhaps elsewhere? And how will it all end? The Universe itself sets the stage for the very interdisciplinary field of astrobiology that attempts to answer such questions, the central one being: What is the (cosmic) recipe for life? Currently there are only very few known elements in this vast mosaic. This book bridges a gap in the literature by bringing together leading specialists from different backgrounds who lecture on their fields, with close relevance to astrobiology, providing tutorial accounts that lead all the way to the forefront of research. The book will thus be useful for students, lecturers and reseachers alike.

Astrophysics: A New Approach

Astrophysics: A New Approach by Wolfgang Kundt
English | PDF | 2001 | 185 Pages | ISBN : N/A | 18.5 MB

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 - these edited lecture notes are perhaps among the most concise and also among the most critical ones: Astrophysics has not yet stood the redundancy test of laboratory physics, hence should be aware of early interpretations. Special chapters are devoted to magnetic and radiation processes, supernovae, 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 for the precise interpretation of frontline phenomena. The author compares mainstream interpretations with new and even controversial ones he wishes to emphasize.

Theory of Orbits: Perturbative and Geometrical Methods by Dino Boccaletti , Giuseppe Pucacco

Half a century ago, S. Chandrasekhar wrote these words in the preface to his 1 celebrated and successful book: In this monograph an attempt has been made to present the theory of stellar dy­ namics as a branch of classical dynamics - a discipline in the same general category as celestial mechanics. [ … ] Indeed, several of the problems of modern stellar dy­ namical theory are so severely classical that it is difficult to believe that they are not already discussed, for example, in Jacobi's Vorlesungen. Since then, stellar dynamics has developed in several directions and at var­ ious levels, basically three viewpoints remaining from which to look at the problems encountered in the interpretation of the phenomenology. Roughly speaking, we can say that a stellar system (cluster, galaxy, etc.) can be con­ sidered from the point of view of celestial mechanics (the N-body problem with N» 1), fluid mechanics (the system is represented by a material con­ tinuum), or statistical mechanics (one defines a distribution function for the positions and the states of motion of the components of the system).

Lectures on Non-linear Plasma Kinetics by Vadim N. Tsytovich
English | PDF | 1995 | 380 Pages | ISBN : 3642789048 | 34.8 MB

Lectures on Non-linear Plasma Kinetics is an introduction to modern non-linear plasma physics showing how many of the techniques of modern non-linear physics find applications in plasma physics and how, in turn, the results of this research find applications in astrophysics. Emphasis is given to explaining the physics of nonlinear processes and the radical change of cross-sections by collective effects. The author discusses new nonlinear phenomena involving the excitation of coherent nonlinear structures and the dynamics of their random motions in relation to new self-organization processes. He also gives a detailed description of applications of the general theory to various research fields, including the interaction of powerful radiation with matter, controlled thermonuclear research, etc.
