This book was released on 2012-12-06 with total page 410 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book contains the lectures presented at the International Workshop on Relation between Laboratory and Space Plasmas held at Gakushi-Kaikan (University Alumni Association) Kanda in Tokyo, Japan on 14 - 15 April, 1980. Its aim was to bring together laboratory, fusion and space plasma physicists and to highlight the communality of basic plasma phenomena, similarities and differences observed in the laboratory and in space, thus exchanging information tnd views on new ideas to link both areas. Although similar type of conferences were held in Europe and recently in the States, this is the first time we have had in Japan for such an international meeting, which may be regarded as an extended version of our national Workshop held twice at the Institute of Plasma Physics of Japan (IPPJ) in 1976 and in 1977 (IPPJ Research Report No. 286 and No. 365). The Workshop consisted of seven regular sessions and one special session with approximately ninety participants from allover the world. Thirty-six papers, invited and contributed, were presented, nine from U. S. A., three from U. S. S. R., two of each from Germany, France, India, one of each from Sweden, Canada, Belgium and fifteen from Japan. The topics covered were: (1) The Critical Velocity (2) Beam Plasma Discharges and Interactions (3) Double Layers and Shocks (4) Instabilities in the Equatorial and Auroral Electrojets (5) Turbulent and Anomalous Plasmas (6) Plasma Irregularities (7) Solar Plasma Phenomena (8) Active Experiments in Space Plasmas and Their Simulation in the Laboratory.
Download or read book Proceedings of the Plasma Space Science Symposium written by C.C. Chang and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 380 pages. Available in PDF, EPUB and Kindle. Book excerpt: Space, whether interplanetary or interstellar, is filled with plasma or ionized gas. The success of space exploration must count heavily on the study and understanding ofthe plasma. With this view, the Symposium ofPlasma Space Science was held at The Catholic University of America in Washington, D.C., in cooperation with the National Aeronautics and Space Administration and the Goddard Space Flight Center, June 11-14, 1963. The symposium was organized by Dr. C. C. Chang as director and Dr. Y. C. Whang as assistant director. The proceedings consist of four parts. The first part describes the solar phenomena: solar magnetic field, flare, atmosphere, cosmic rays, radiation, etc. The second part deals with the solar wind or interplanetary plasma. This includes both theoretical treatment and experimental measurements of Mariner H. The third part is concen trated on magnetosphere, with the measurements on trapped radiation from natural sources and high altitude thermonuclear explosions, and particularly with the magnetopause. The fourth and last part includes the ring current, geomagnetic storms, the aurora, the ionosphere and lunar surface phenomena. There was round table discussion in each session. Many interesting comments and stimulating arguments emerged from the floor and are included in the Proceedings.

This book was released on 2012-12-06 with total page 291 pages. Available in PDF, EPUB and Kindle. Book excerpt: This special issue of the international journal of cosmic physics, Astrophysics and Space Science, contains invited contributions delivered at the Second IEEE International Workshop on Plasma Astrophysics and Cosmology, held from 10 to 12 May 1993 in Princeton, New Jersey. The Workshop was sponsored by the NSF Division of Atmospheric Sciences, NASA Headquarters, Space Physics Division, and the Nuclear and Plasma Sciences Society of the Institute of Electrical and Electronics Engineers. It was the purpose of the Workshop to update topics in Plasma Astrophysics and Cosmology presented at the First IEEE International Workshop on Plasma Cosmology, La Jolla, California, 20-22 February 1989, and to again bring together observers and theorists to discuss the related links between plasma theory and observation. Another goal of the Workshop and these proceedings was to highlight the Centennial Celebration (1896-1996) of the founding of Plasma Astrophysics and Cosmology and several papers are devoted to the history of this field of science.

Available in PDF, EPUB and Kindle. Book excerpt: This volume contains all but one of the lectures and seminars presented at the NATO Advanced Study Institute on HOI Thin Plasmas in Astrophysics held in Cargese, Corsica, from September 8 to 18, 1987. The meeting was planned in collaboration with the members of the Scientific Organizing Committee, 10 whom I am grateful for suggesting a comprehensive and well balanced program. The SOC was comprised of Prof. J. Bleeker (Space Research Institute. Utrecht, The Netherlands), Dr. C. Cesarsky (CEN Saclay, France), Dr. R. Mushotzky (GSFC, USA), Prof. K. Pounds (University of Leicester, UK), Prof. H. Schnopper (Danish Space Research Laboratory, Denmark), Dr. H. Tananbaum (Center for Astrophysics, USA), Dr. G. Trinchieri (Arcetri Observatory, Italy), and Prof. 1. Truemper (MPE, Garching, Germany). The ASI, fully supported by the NATO Scientific Affairs Division, was organized with the intent of providing a critical and up-to-date overview of our present kowledge and understanding of the properties of hot thin plasmas in astrophysics as they are revealed by X-ray observations from space. The X-ray and UV emission from optically thin thermal plasmas is a common feature of many astrophysical systems. This type of emission occurs in the solar corona and in the coronae of other stars, in supernova remnants and in the hot interstellar medium, in normal galaxies and galactic halos, and in the intergalactic gas in clusters.
Download or read book Physical Processes in Hot Cosmic Plasmas written by W. Brinkmann and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 446 pages. Available in PDF, EPUB and Kindle. Book excerpt: Gas at temperatures exceeding one million degrees is common in the Universe. Indeed it is likely that most of the gas in the Universe exists in intergalactic space in this form. Such highly-ionized gas, or plasma, is not restricted to the rarefied densities of intergalactic space, but is also found in clusters of galaxies, in galaxies themselves, in the expanding remnants of exploded stars and at higher densities in stars and the collapsed remains of stars up to the highest densities known, which occur in neutron stars. The abundant lower-Z elements, at least, in such gas are completely ionized and the gas acts as a highly conducting plasma. It is therefore subject to many cooperative phenomena, which are often complicated and ill-understood. Many of these processes are, however, well-studied (if not so well-understood) in laboratory plasmas and in the near environment of the Earth. Astronomers therefore have much to learn from plasma physicists working on laboratory and space plasmas and the parameter range studied by the plasma physicists might in turn be broadened by contact with astronomers. With that in mind, a NATO Advanced Research Workshop on Physical Processes in Hot Cosmic Plasmas was organized and took place in the Eolian Hotel, Vulcano, Italy on May 29 to June 2 1989. This book contains the Proceedings of that Workshop.

This book was released on 2012-12-06 with total page 470 pages. Available in PDF, EPUB and Kindle. Book excerpt: Interest in the problem of interaction between radiation and astrophysical plasmas arose decades ago. Initially, this was closely related to the discovery of radio emission from the Sun and Galaxy which alerted theoretical radio astronomers to the problem of the origin of extra-terrestrial radio emission. It has been found that the observed radio emission from cosmic sources is generated by virtue of the mechanisms which work mainly in plasma (an ionized gas). Recently, the theory of generation and propagation of radiation in astrophysical plasmas has outgrown its parent domain of theoretical radio astronomy and is being successfully applied to other fields, such as high-energy astrophysics. General results obtained in this field may also help to better understand the complicated phenomena in laboratory plasmas on the Earth. At the same time, analysis of interaction between radiation and astrophysical plasmas under extreme conditions (strong magnetic fields of white dwarfs and neutron stars or strong gravitational fields in the vicinity of black holes) stimulates the development of plasma physics as a whole. In fact, the physics of plasma under extreme conditions in space is a new branch of fundamental science. The monograph contains the description of physical processes involved in interaction between radiation and astrophysical plasmas. It comprises the reasonable minimum necessary for understanding the emission and propagation of electromagnetic waves in astrophysical plasmas; without this minimum one could not succeed in interpreting the results of a number of astronomical observations. Audience: This monograph will be useful for graduate and post-graduate students and young scientists as a textbook on plasma astrophysics and the issues of plasma physics dealing with radiation. At the same time, the book can be used by specialists on astrophysics, radio astronomy and plasma physics.
Download or read book Cosmic Plasma written by H. Alfvèn and published by Taylor & Francis. This book was released on 1981-02-28 with total page 202 pages. Available in PDF, EPUB and Kindle. Book excerpt: The general background of this monograph and the aim of it is described in detail in Chapter I. As stated in 1.7 it is written according to the principle that "when rigour appears to conflict with simplicity, simplicity is given preference", which means that it is intended for a rather broad public. Not only graduate students but also advanced undergraduates should be able to understand at least most of it. This monograph is the result of many years of inspiring discussions with a number of colleagues, for which I want to thank them very much. Especially I should mention the groups in Stockholm and La Jolla: in Stockholm, Dr Carl-Gunne Flilthammar and many of his collaborators, including Drs Lars Block, Per Carlqvist, Lennart lindberg, Michael Raadu, Staffan Torven, Miroslav Babic, and Itlgvar Axniis, and further, Drs Bo Lehnert and Bjorn Bonnevier, all at the Royal Institute of Technology. Of other col leagues in Sweden, I should mention Dr Bertel Laurent, Stockholm University, Dr Aina Elvius, The Stockholm Observatory, and Dr Bengt Hultqvist, Kiruna. In La Jolla my thanks go first of all to Dr Gustaf Arrhenius, who once invited me to La Jolla, which was the start of a most interesting collaboration; further, to Dr W. B.

Download or read book Plasma Astrophysics written by Arnold O. Benz and published by Springer. This book was released on 2014-04-21 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: This textbook is intended as an introduction to the physics of solar and stellar coronae, emphasizing kinetic plasma processes. It is addressed to observational astronomers, graduate students, and advanced undergraduates without a ba- ground in plasma physics. Coronal physics is today a vast field with many different aims and goals. So- ing out the really important aspects of an observed phenomenon and using the physics best suited for the case is a formidable problem. There are already several excellent books, oriented toward the interests of astrophysicists, that deal with the magnetohydrodynamics of stellar atmospheres, radiation transport, and radiation theory. In kinetic processes, the different particle velocities play an important role. This is the case when particle collisions can be neglected, for example in very brief phenomena – such as one period of a high-frequency wave – or in effects produced by energetic particles with very long collision times. Some of the most persistent problems of solar physics, like coronal heating, shock waves, flare energy release, and particle acceleration, are likely to be at least partially related to such p- cesses. Study of the Sun is not regarded here as an end in itself, but as the source of information for more general stellar applications. Our understanding of stellar processes relies heavily, in turn, on our understanding of solar processes. Thus an introduction to what is happening in hot, dilute coronae necessarily starts with the plasma physics of our nearest star.

This report proposes a broad, integrated plan for space- and ground-based astronomy and astrophysics for the decade 2023-2032. It also lays the foundations for further advances in the following decade.
Download or read book Astrophysical Lasers written by Vladilen Letokhov and published by OUP Oxford. This book was released on 2008-12-18 with total page 272 pages. Available in PDF, EPUB and Kindle. Book excerpt: Progress in modern radio astronomy led to the discovery of space masers in the microwave range, and it became a powerful tool for studies of interstellar star-forming molecular clouds. Progress in observational astronomy, particularly with ground-based huge telescopes and the space-based Hubble Space Telescope, has led to recent discoveries of space lasers in the optical range. These operate in gas condensations in the vicinity of the mysterious star Eta Carinae (one of the most luminous and massive stars of our Galaxy). Both maser and laser effects, first demonstrated under laboratory conditions, have now been discovered to occur under natural conditions in space too. This book describes consistently the elements of laser science, astrophysical plasmas, modern astronomical observation techniques, and the fundamentals and properties of astrophysical lasers. A book with such an interdisciplinary scope has not been available to date. The book will also be useful for a wider audience interested in modern developments of the natural sciences and technology.

Available in PDF, EPUB and Kindle. Book excerpt: The principal goals of the study were to articulate the scientific rationale and objectives of the field and then to take a long-term strategic view of U.S. nuclear science in the global context for setting future directions for the field. Nuclear Physics: Exploring the Heart of Matter provides a long-term assessment of an outlook for nuclear physics. The first phase of the report articulates the scientific rationale and objectives of the field, while the second phase provides a global context for the field and its long-term priorities and proposes a framework for progress through 2020 and beyond. In the second phase of the study, also developing a framework for progress through 2020 and beyond, the committee carefully considered the balance between universities and government facilities in terms of research and workforce development and the role of international collaborations in leveraging future investments. Nuclear physics today is a diverse field, encompassing research that spans dimensions from a tiny fraction of the volume of the individual particles (neutrons and protons) in the atomic nucleus to the enormous scales of astrophysical objects in the cosmos. Nuclear Physics: Exploring the Heart of Matter explains the research objectives, which include the desire not only to better understand the nature of matter interacting at the nuclear level, but also to describe the state of the universe that existed at the big bang. This report explains how the universe can now be studied in the most advanced colliding-beam accelerators, where strong forces are the dominant interactions, as well as the nature of neutrinos.
