Abstract

Abstract

From the data observed by Helios et al. during 1972 to 1987, 986 interplanetary fast shocks are picked out and the most appropriate polytropic index for every shock is determined by applying MHD Rankine-Hugoniot relations. The results demonstrate that the values of polytropic index scatter in a certain range, and the most probable value is approximately between 1.70 and 1.75.
