Distilled shock conditions for ideal magneto-acoustic shock waves in an optically thick medium

Abstract

The shock waves are important features in the analysis of transonic magnetohydrodynamical (MHD) flows where thermal radiation could also be significant. In this paper the effects of black-body radiation on non-relativistic shock waves in an ideal radiation MHD model for the optically thick case are discussed. Distilled shock conditions were derived and discussed for the case of a fixed ratio of specific heats of an ideal gas (gamma) and ratio of gas to total pressure (b). The special case, when jumps in gamma and/or b are allowed, was also considered.
