On transient relativistic thermodynamics and kinetic theory. Il

Abstract

This paper, the sequel to Stewart (1977), discusses the relation between transient relativistic thermodynamics and kinetic theory in the formulation of Israel (1972, 1976) which differs (mathematically) from that of the previous paper. The difference is that the moment expansions are truncated in different ways. However, identical results for the characteristic velocities of thermal transients are obtained, and this lends credence to both approaches. In this approximation at least, the Grad method of moments is insensitive to the truncation procedure.
