Description
Analytical approximations and 2D hydrodynamical simulations are used to
examine the interaction of supernova fragments with the internal
structure of large multisupernova remnants (MSRs). The fragments are
thermalized by reverse shocks generated in the interaction with the MSR
interior, which is assumed to be hot and rarefied. The evolution is
divided into two stages: before and after reaching a reference distance,
R(E), from the explosion site. As the density of the expanding fragment
drops, the reverse shock accelerates, and, when the distance R(E) is
reached, it begins to effectively erode the fragment. At some selected
evolutionary times, the X-ray emission from the shocked fragment is also
calculated. The direct bombardment of the MRS shell by the shocked
fragment has a series of important consequences: it excites, punctures,
and deforms the expanding shell.
