THE STABILITY AND EVOLUTION OF MAGNETOHYDRODYNAMICS,

Abstract

Shock waves in a rarified plasma within a very strong magnetic field (coinciding with the wave front plane) are discussed. Here one can neglect all dissipative effects with the exception of Joule heating caused by electron-ion collisions. In the case of low effective electron-ion collision frequencies the shock wave front has an oscillatory structure. The paper discusses: (1) the high collision frequency case when one can apply the evolutionary conditions of ordinary magnetohydrodynamics; and (2) the case when, within a sufficiently rarified plasma, there exist weakly damped perturbations with frequencies comparable to the ionic Larmor frequency omega sub H. In this last case, the analysis must take into account dispersion effects near omega sub H. (Author)
