Description
The evolution of supernova remnants in preexisting cavities is examined
by means of 1D and 2D numerical studies of the phenomenon and the
fragmentation of ejecta. The analytical approach involves approximating
the cavity produced by an adiabatic blast with a power-law density
distribution. The numerical studies that follow model a single supernova
inside a 'normal' bubble with both fragmented and unfragmented ejecta. A
standard supernova-remnant evolutionary path cannot be described because
the initial conditions affect the thermal conditions that follow ejecta
thermalization. The evolutionary appearance of supernova remnants is
found to be highly dependent on the existence of a massive wind-driven
shell. The results of the numerical models are concluded to be an
appropriate framework within which to study the supernova remnants with
observational data.
