Book Description
The presentation begins by considering the requirements on the acceleration mechanism. It is found that at least some particles in high-energy sources are accelerated by magnetic reconnection (and not by shocks). The two paradigms can be distinguished by the hardness of the spectra. Shocks typically produce spectra with p> 2 (relativistic shocks have p ~ 2.2); non-linear shocks & drift acceleration may give p

Book Description
Photo acceleration has dominated the theoretical plasma physics area in recent years and has found application in all subjects where waves in continuous media are studied - plasma physics, astrophysics, and optics. This theory will provide a modern understanding of photon interaction with matter, helping to develop novel accelerators based on laser-plasma interactions, new radiation sources, and even new models for astrophysical objects. Written by a major player in the field, this book describes the general theory of photo acceleration, which allows fluid, kinetic, quantum, and classical electrodynamical approaches to be formulated. It includes examples from plasma physics, cosmology, fiber optics, mathematical physics, particle accelerator physics, and radiation physics.

Book Description
This unusual book considers physical principles, starting from the most general ones, and simplifies assumptions, helping students answer two key questions: what approximation is the simplest, but still sufficient for the description of a phenomenon in cosmic plasmas, and how to build an adequate model.

Book Description
Chapter 1 briefly describes the main properties of space plasmas and primary CR. Chapter 2 considers the problem of CR propagation in space plasmas described by the kinetic equation and different types of diffusion approximations. Chapter 3 is devoted to CR non-linear effects in space plasmas caused by CR pressure and CR kinetic stream instabilities with the generation of Alfvèn turbulence. In Chapter 4 different processes of CR acceleration in space plasmas are considered. The book ends with a list providing more than 1,300 full references, a discussion on future developments and unsolved problems, as well as Object and Author indexes.

Book Description
Solar and space physics is the study of solar system phenomena that occur in the plasma state. Examples include sunspots, the solar wind, planetary magnetospheres, radiation belts, and the aurora. While each is a distinct phenomenon, there are commonalities among them. To help define and systematize these universal aspects of the field of space physics, the National Research Council was asked by NASA's Office of Space Science to provide a scientific assessment and strategy for the study of magnetized plasmas in the solar system. This report presents that assessment. It covers a number of important research goals for solar and space physics. The report is complementary to the NRC report, The Sun to the Earthâ€"and Beyond: A Decadal Research Strategy for Solar and Space Physics, which presents priorities and strategies for future program activities.

Book Description
During the past decade our understanding of plasma physics has witnessed an explosive growth due to research in two areas: work directed toward controlled nuclear fusion and work in space physics. This book addresses the growing need to apply these complementary discoveries to astrophysics. Today plasma is recognized as the key element to understanding the generation of magnetic fields in planets, stars and galaxies, the accel- eration and transport of cosmic rays, and many other phenomena occurring in interstellar space, in radio galaxies, stellar atmospheres, quasars, and so forth.
