Study Theoretical of Supernova Remnants(1987A)

Abstract

In these research expansion of the supernova(1987A)in the interstellar matter has been studied .And also the degeneration in ejects velocity with the increasing of degeneration distance from the center of explosion have been studied. And it found to be the ejects shell velocity equals (10800 km/sec ), its radius (0.0648 Pc )and its temperature(1.3x1010 K),the results showed a good agreement with the published and depending results. The result shows that this supernova remnants still in radiation cooling expansion phase by using poveda model.
