Scientific paper

The interaction of a supernova shock with its surrounding medium produces X-ray emission which also probes the environment. The soft X-rays arise either from the heating of the exploding star's ejecta by a reverse shock propagating into it, or alternatively, due to the radiative cooling of clumped, pre-existing clouds crushed by the shocked circumstellar wind. The ionized plasma emission linewidths, abundance of elements in the radiating zone and the temporal evolution of the X-ray luminosity are diagnostics to discriminate between the two models. We request a 55 ksec Chandra ACIS spectroscopic observation of a radio loud, X-ray bright supernova SN1995N towards this goal. Additionally this will constrain the mass of the progenitor star by measuring the nucleosynthetic yields.
