Physics of the Plasma Universe
|Author||Anthony L Peratt|
"The purpose of this book is to address the growing recognition of the need for plasma physics in astrophysics. In fact, astrophysics has contributed to the growth of plasma physics, especially in the field of plasma waves . During the last decade, plasma physics, or more appropriately, plasma science, has witnessed an explosive growth in two areas : pulsed-power technology and space physics. Both have led to knowledge that is mutual and complementary, and the material in this book largely derives from these new discoveries and their application to astrophysics. [..]
"Today plasma is recognized as the key element to understanding the generation of magnetic fields in planets, stars, and galaxies; phenomena occurring in stellar atmospheres, in the interstellar and intergalactic media, in radio galaxies, in quasars, and in active galactic nuclei ; and the acceleration and transport of cosmic rays . There are convincing arguments for the view that the clouds out of which galaxies form and stars condense are ionized : The problem of the formation and structure of these clouds and bodies, therefore, naturally belongs to the field of cosmic plasmas as well as astrophysics.

"Together these problems form what is called The Plasma Universe, the basis for this book . The material presented dwell s basically on the known properties of matter in the plasma state. Some of the interesting topics in contemporary astrophysics such as discordant redshifts and other cosmological issues are not discussed here . The interested reader will be referred to the IEEE Transactions on Plasma Science, Special Issues on Space and Cosmic Plasmas (December 1986, April 1989, and February 1990), and Laser and Particle Beams (August 1988).

"This book is organized into eight chapters. Chapter 1 is an introduction to the fundamental physics of cosmic plasmas . An attempt is made to review the known properties of plasmas from the laboratory scale to the Hubble distance. Chapter 2 starts the application of basic plasma theory to astrophysical plasmas in the study o f magnetic-field-aligned (Birkeland) currents and charged particle beams . Chapter 3 covers magnetism in plasma and the Biot-Savart force law, while Chapter 4 concen - trates on electric fields in space and cosmic plasmas . Chapters 5, 6, and 7 survey double layers, synchrotron radiation, and energy transport in plasmas, respectively. Chapter 8 covers the particle-in-cell simulation of astrophysical plasmas. Found throughout the book are examples that apply the material of the chapter or section to specific problems."
