Available in PDF, EPUB and Kindle. Book excerpt: The present book provides a contemporary systematic treatment of shock waves in high-temperature collisionless plasmas as are encountered in near Earth space and in Astrophysics. It consists of two parts. Part I develops the complete theory of shocks in dilute hot plasmas under the assumption of absence of collisions among the charged particles when the interaction is mediated solely by the self-consistent electromagnetic fields. Such shocks are naturally magnetised implying that the magnetic field plays an important role in their evolution and dynamics. This part treats subcritical shocks which dissipate flow energy by generating anomalous resistance or viscosity. The main emphasis is, however, on super-critical shocks where the anomalous dissipation is insufficient to retard the upstream flow. These shocks, depending on the direction of the upstream magnetic field, are distinguished as quasi-perpendicular and quasi-parallel shocks which exhibit different behaviours, reflecting particles back upstream and generating high electromagnetic wave intensities. Particle acceleration and turbulence at such shocks become possible and important. Part II treats planetary bow shocks and the famous Heliospheric Termination shock as examples of two applications of the theory developed in part I.

Download or read book Characterizing Space Plasmas written by George K. Parks and published by Springer. This book was released on 2018-07-26 with total page 332 pages. Available in PDF, EPUB and Kindle. Book excerpt: This didactic book uses a data-driven approach to connect measurements made by plasma instruments to the real world. This approach makes full use of the instruments’ capability and examines the data at the most detailed level an experiment can provide. Students using this approach will learn what instruments can measure, and working with real-world data will pave their way to models consistent with these observations. While conceived as a teaching tool, the book contains a considerable amount of new information. It emphasizes recent results, such as particle measurements made from the Cluster ion experiment, explores the consequences of new discoveries, and evaluates new trends or techniques in the field. At the same time, the author ensures that the physical concepts used to interpret the data are general and widely applicable. The topics included help readers understand basic problems fundamental to space plasma physics. Some are appearing for the first time in a space physics textbook. Others present different perspectives and interpretations of old problems and models that were previously considered incontestable. This book is essential reading for graduate students in space plasma physics, and a useful reference for the broader astrophysics community.

Book excerpt: Collisionless shock waves are a very important heating mechanism for plasmas and are commonly found in space and astrophysical environments. Collisionless shocks were studied in the laboratory more than 20 years ago, and more recently in space via in situ satellite measurements. The authors propose a new laboratory shock wave experiment to address unresolved issues related to the differences in the partition of plasma heating between electrons and ions in space and laboratory plasmas, which can have important implications for a number of physical systems.

Download or read book Laser Produced Plasmas as Drivers of Quasi Parallel Collisionless Shock Formation in the Laboratory written by Peter Ver Bryck Heuer and published by . This book was released on 2020 with total page 164 pages. Available in PDF, EPUB and Kindle. Book excerpt: Quasi-parallel collisionless shocks are objects of considerable interest in space and astrophysics, most notably as possible sites of cosmic ray acceleration. Such shocks occur naturally in systems such as supernova remnants and planetary bow shocks, where the complex and turbulent structures they form are commonly observed by spacecraft. However, \textit{in situ} spacecraft measurements have some inherent limitations, such as a moving reference frame and non-repeatable measurements. Generating a quasi-parallel collisionless shock in a repeatable, well-diagnosed laboratory environment could therefore improve our understanding of their formation and structure. The quasi-parallel collisionless shocks observed in space and astrophysics are far too large to fit in a laboratory, but scaled versions of these systems can be created using smaller, denser plasmas with similar dimensionless parameters. However, quasi-parallel collisionless shocks are particularly challenging to scale to a feasible experiment. The shock formation process is mediated by several electromagnetic ion/ion beam instabilities which require long length scales ($>500$ ion-inertial lengths) to grow, so an experiment must include a long magnetized background plasma. This background plasma must be overlapped over the same length by a highly super-Alfv\'enic beam plasma. Matching the dimensionless parameters of the shocks observed in space sets demanding requirements on the densities of both plasmas as well as the background magnetic field strength. Laser-produced plasmas (LPPs) provide a promising beam plasma source (a ``driver'') for such experiments. A recent experimental campaign has been conducted at UCLA to investigate the potential of LPPs as drivers of quasi-parallel collisionless shocks. These experiments combine one of two high-energy lasers with the magnetized background plasma of the Large Plasma Device (LAPD) to drive the electromagnetic ion/ion beam instabilities responsible for shock formation. The experiments have observed electromagnetic waves consistent with the very early stages of quasi-parallel shock formation. These waves are similar to the ultra-low frequency (ULF) waves observed by spacecraft upstream of the Earth's quasi-parallel bow shock. At present, the amplitudes of the waves generated by these experiments are too low ($dB/B_0 \sim 0.01$) to fully form a quasi-parallel shock. The wave amplitudes observed in these experiments are low because the conditions for beam instability growth are only met in a small region near the laser target. Outside of this region, decreasing LPP density due to velocity dispersion and cross-field transport terminates the wave growth and consequently the shock formation process. Future experiments will require technical innovations to expand this growth region in order to produce larger-amplitude waves. Promising approaches including trains of laser pulses and heating electrons in the background plasma to reduce collisional cross-field transport. Along with comparisons to analytic theory and simulations, the results of the current experiments can inform the design of future laboratory quasi-parallel shock experiments.
Download or read book Collisionless Plasmas in Astrophysics written by Gérard Belmont and published by John Wiley & Sons. This book was released on 2013-09-10 with total page 389 pages. Available in PDF, EPUB and Kindle. Book excerpt: Collisionless Plasmas in Astrophysics examines the unique properties of media without collisions in plasma physics. Experts in this field, the authors present the first book to concentrate on collisionless conditions in plasmas, whether close or not to thermal equilibrium. Filling a void in scientific literature, Collisionless Plasmas in Astrophysics explains the possibilities of modeling such plasmas, using a fluid or a kinetic framework. It also addresses common misconceptions that even professionals may possess, on phenomena such as "collisionless (Landau) damping". Abundant illustrations are given in both space physics and astrophysics.

Download or read book Low Frequency Waves in Space Plasmas written by Andreas Keiling and published by John Wiley & Sons. This book was released on 2016-04-04 with total page 524 pages. Available in PDF, EPUB and Kindle. Book excerpt: Low-frequency waves in space plasmas have been studied for several decades, and our knowledge gain has been incremental with several paradigm-changing leaps forward. In our solar system, such waves occur in the ionospheres and magnetospheres of planets, and around our Moon. They occur in the solar wind, and more recently, they have been confirmed in the Sun’s atmosphere as well. The goal of wave research is to understand their generation, their propagation, and their interaction with the surrounding plasma. Low-frequency Waves in Space Plasmas presents a concise and authoritative up-to-date look on where wave research stands: What have we learned in the last decade? What are unanswered questions? While in the past waves in different astrophysical plasmas have been largely treated in separate books, the unique feature of this monograph is that it covers waves in many plasma regions, including: Waves in geospace, including ionosphere and magnetosphere Waves in planetary magnetospheres Waves at the Moon Waves in the solar wind Waves in the solar atmosphere Because of the breadth of topics covered, this volume should appeal to a broad community of space scientists and students, and it should also be of interest to astronomers/astrophysicists who are studying space plasmas beyond our Solar System.
Download or read book Basic Space Plasma Physics Revised Edition written by Wolfgang Baumjohann and published by World Scientific Publishing Company. This book was released on 2012-03-20 with total page 496 pages. Available in PDF, EPUB and Kindle. Book excerpt: This textbook begins with a description of the Earth's plasma environment, followed by the derivation of single particle motions in electromagnetic fields, with applications to the Earth's magnetosphere. Also discussed are the origin and effects of collisions and conductivities, formation of the ionosphere, magnetospheric convection and dynamics, and solar wind-magnetosphere coupling.The second half of the book presents a more theoretical foundation of plasma physics, starting with kinetic theory. Introducing moments of distribution function permits the derivation of the fluid equations, followed by an analysis of fluid boundaries, with the Earth's magnetopause and bow shock as examples, and finally, fluid and kinetic theory are applied to derive the relevant wave modes in a plasma.This revised edition seamlessly integrates new sections on magnetopause reconstruction, as well as instability theory and thermal fluctuations based on new developments in space physics. Applications such as the important problems of collisionless reconnection and collisionless shocks are covered, and some problems have also been included at the end of each chapter.
Download or read book Physics Of Space Plasmas written by George Parks and published by Westview Press. This book was released on 2003-12-05 with total page 616 pages. Available in PDF, EPUB and Kindle. Book excerpt: In its inaugural edition, Physics of Space Plasmas was the most widely used textbook for courses in space plasma physics, and included up-to-date observations from space available at the time. Throughout universities in the United States and abroad-it has proven itself indispensable. In the more than ten years since, an amazing number of new space plasma observations have been made. These more recent observations have revealed new and exciting information about space plasma. Now, incorporating new information from several NASA and ESA space missions, the completely revised second edition is expanded to include kinetic physics so that kinetic features in the plasma data can be explained more clearly. In addition, Parks now includes a clear and simple discussion of how electromagnetic fields behave in rotating frames. This thoroughly revised second edition retains the thoughtful examples and problems of the first edition and expands to include new examples, problem sets, schematic diagrams, and images that complement the new material.
