Theory and simulation of collisionless parallel shocks
TLDR
In this paper, a self-consistent theoretical model for collisionless parallel shock structure, based on the hypothesis that shock dissipation and heating can be provided by electromagnetic ion beam-driven instabilities, is presented.Abstract:
This paper presents a self-consistent theoretical model for collisionless parallel shock structure, based on the hypothesis that shock dissipation and heating can be provided by electromagnetic ion beam-driven instabilities. It is shown that shock formation and plasma heating can result from parallel propagating electromagnetic ion beam-driven instabilities for a wide range of Mach numbers and upstream plasma conditions. The theoretical predictions are compared with recently published observations of quasi-parallel interplanetary shocks. It was found that low Mach number interplanetary shock observations were consistent with the explanation that group-standing waves are providing the dissipation; two high Mach number observations confirmed the theoretically predicted rapid thermalization across the shock.read more

Nonlinear theory of diffusive acceleration of particles by shock waves
Mikhail Malkov,L. O'c. Drury +1 more
TL;DR: In this article, a review of the current theoretical understanding of this process, from the basic ideas of how a shock energizes a few reactionless particles to the advanced nonlinear approaches treating the shock and accelerated particles as a symbiotic self-organizing system, is presented.

The plasma physics of shock acceleration
Frank C. Jones,Donald C. Ellison +1 more
TL;DR: In this paper, a review of the history and theory of particle acceleration is presented, paying particular attention to theories of parallel shocks which include the backreaction of accelerated particles on the shock structure, and the work that computer simulations, both plasma and Monte Carlo, are playing in revealing how thermal ions interact with shocks.

Particle Acceleration by Astrophysical Shocks
TL;DR: In this article, a new mechanism is proposed for acceleration of a power-law distribution of cosmic rays with approximately the observed slope, where high-energy particles in the vicinity of a shock are scattered by Alfven waves carried by the converging fluid flow leading to a first-order acceleration process in which the escape time is automatically comparable to the acceleration time.
