Properties of supernova remnants (SNRs) in the late stages of evolution are determined mainly by
the energy of Supernova explosion, the physical characteristics of the interstellar medium (density,
pressure, etc.), where the expansion of the shock wave takes place, as well as the nature of the
physical processes occurring at the shock front in the early stages of the evolution of SNR. SNRs in
the late stages are almost stationary objects, so the evolution of such objects can be studied by
means of statistical methods.
In the late stages of their evolution, SNRs are expected to develop
dense shells which emit in the optical range and HI 21-cm line. Recently in these ranges a large
number of SNRs are identified in nearby galaxies. In this presentation we report the results of
modeling of SNR statistics by using the Monte Carlo technique and of their comparison with the
observed statistics of real SNRs.
