TEMPERATURE ANISOTROPY EFFECTS AND THE GENERATION OF ANOMALOUS SLOW SHOCKS

Temperature anisotropy is a persistent feature df many space plasmas ( e.g., the magnetosheath) and can result in significant modifications t o the jump conditions at various discontinuities. The effect of anisot ropy on the Rankine-Hugoniot (RH) relations is reexamined and the topo logical changes in the solutions are illustrated by means of a graphic al technique. A class of slow shocks is found with quite unusual prope rties. In particular, there exists a class of nonswitchoff slow shocks which rotate the tranverse component of the magnetic field. To distin guish these new solutions from the usual solutions, they are termed an omalous slow shocks.
