Available in PDF, EPUB and Kindle. Book excerpt: Published by the American Geophysical Union as part of the Geophysical Monograph Series, Volume 35. Violent expansions of the solar corona cause transient shock waves which propagate outward from the sun at hundreds to thousands of kilometers per second; simple solar wind velocity gradients at the surface of the sun lead to high-speed streams overtaking slower streams, forming corotating shocks; and steady state supermagnetosonic solar wind flow past objects such as the planets lead to standing bow shocks. However, the solar wind plasma is so hot and tenuous that charged particle Coulomb collisions produce negligible thermalization or dissipation on scale sizes less than 0.1 AU. The irreversible plasma heating by these shocks is accomplished by wave-particle interactions driven by plasma instabilities. Hence these shocks are described as "collisionless."

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 Collisionless Shocks in Space Plasmas written by David Burgess and published by Cambridge University Press. This book was released on 2015-07-30 with total page 367 pages. Available in PDF, EPUB and Kindle. Book excerpt: Shock waves are an important feature of solar system plasmas, from the solar corona out to the edge of the heliosphere. This engaging introduction to collisionless shocks in space plasmas presents a comprehensive review of the physics governing different types of shocks and processes of particle acceleration, from fundamental principles to current research. Motivated by observations of planetary bow shocks, interplanetary shocks and the solar wind termination shock, it emphasises the physical theory underlying these shock waves. Readers will develop an understanding of the complex interplay between particle dynamics and the electric and magnetic fields that explains the observations of in situ spacecraft. Written by renowned experts in the field, this up-to-date text is the ideal companion for both graduate students new to heliospheric physics and researchers in astrophysics who wish to apply the lessons of solar system shocks to different astrophysical environments.

Available in PDF, EPUB and Kindle. Book excerpt: Until the advent of space physics, astrophysical plasmas could be studied only using ground-based observations. Although observational methods have advanced over recent decades, the merging of heliospheric physics with astrophysics is far from complete due to the vastly different techniques employed by astronomers and space physicists. That astrophysical plasmas can be studies directly is a major advance in astrophysical research. The solar wind from the Sun is only one of many examples of solar winds, but it provides scientists with a basis for understanding how these formerly disparate disciplines are related. Cosmic Winds and the Heliosphere is a comprehensive sourcebook on conceptually correlated topics in astrophysical winds and heliospheric physics. The contributors review the various kinds of winds, such as solar wind, winds of cataclysmic variables, and winds from pulsating stars. They then examine the physics of wind origin and physical phenomena in winds. including heliospheric shocks, magnetohydrodynamic turbulence, and kinetic phenomena. A final section considers interactions with surrounding media, with contributions ranging from studies of the interstellar cloud surrounding the solar system to considerations of solar wind interaction with comets. Prepared to the scrupulous standards of the University of Arizona Space Science Series, Cosmic Winds and the Heliosphere is an essential volume for astronomers and space physicists.

Book excerpt: This volume represents the state of the art of the science covered by the International Association of Geomagnetism and Aeronomy (IAGA) Division IV: Solar Wind and Interplanetary Field. It contains a collection of contributions by top experts addressing and reviewing a variety of topics included under the umbrella of the division. It covers subjects that extend from the interior of the Sun to the heliopause, and from the study of physical processes in the Sun and the solar wind plasma to space weather forecasts. The book is organized in 6 parts: the solar interior, the solar atmosphere, the heliosphere, heliophysical processes, radio emissions, and coordinated science in the Sun-Earth system. In addition, we highlight some of the results presented during the IAGA Division IV symposia in the 11th Scientific Assembly of IAGA in Sopron, Hungary, on 23-30 August 2009, which was planned simultaneously with this book.
Download or read book Space Physics written by May-Britt Kallenrode and published by Springer Science & Business Media. This book was released on 2013-03-09 with total page 369 pages. Available in PDF, EPUB and Kindle. Book excerpt: Observations and physical concepts are interwoven to give basic explanations of phenomena and also show the limitations in these explanations and identify some fundamental questions. Compared to conventional plasma physics textbooks this book focuses on the concepts relevant in the large-scale space plasmas. It combines basic concepts with current research and new observations in interplanetary space and in the magnetospheres. Graduate students and young researchers starting to work in this special field of science, will find the numerous references to review articles as well as important original papers helpful to orientate themselves in the literature. Emphasis is on energetic particles and their interaction with the plasma as examples for non-thermal phenomena, shocks and their role in particle acceleration as examples for non-linear phenomena. This second edition has been updated and extended. Improvements include: the use of SI units; addition of recent results from SOHO and Ulysses; improved treatment of the magnetosphere as a dynamic phenomenon; text restructured to provide a closer coupling between basic physical concepts and observed complex phenomena.

Download or read book The Formation of Parallel and Perpendicular Collisionless Shocks in the Big Red Ball written by Douglass Andrew Endrizzi and published by . This book was released on 2021 with total page 157 pages. Available in PDF, EPUB and Kindle. Book excerpt: Collisionless shocks have been observed both in simulations and in spacecraft observations to exhibit strong ripples and undergo cyclic reformation processes. For a nonstationary shock that frequently reforms, the formation mechanism becomes an important part of the overall time averaged shock structure. Two laboratory pulsed power experiments designed to investigate collisionless shock formation mechanisms were performed: the first by using a theta pinch compressing a cylindrical plasma, and the second with a coaxial plasma gun firing into a plasma along the magnetic field direction. These two configurations, where the shock normal is first perpendicular and second parallel to the magnetic field, allow for full exploration of the range of shock geometries. The results from both experiments can be mostly explained by Hall-Magnetohydrodynamic theory, describing magnetized fluid electrons and ions that are unmagnetized on either spatial or temporal scales. Reflected ions are a distinct feature of both experiments, as are Hall currents and whistler waves (both Hall-MHD phenomena). Comparing dimensionless parameters (plasma beta, alfvén Mach number, magnetic Reynolds number) between these laboratory experiments and heliospheric shocks indicate that the observations here may hold particular relevance to interplanetary and bow shocks. Suggested upgrades that might extend the experiment durations to several ion cyclotron periods are presented.
