Petruk O. Hydrodynamic modelling the evolution of supernova remnants in the nonuniform interstellar medium

Supernova remnants. Hydrodynamic modelling of the supernova remnants in media with a large-scale gradient of density. The method of the investigation is the method for calculation of the strong assymetric point explosion in a nonuniform medium developed in the thesis. Method for the full hydrodynamic description of the nonspherical remnants in the medium with an arbitrary distribution of the density is developed. General features of the morphological and X-ray emission evolution of the remnants are revealed. The models of the remnants RCW86, Tycho and IC443 including the nonuniform interstellar medium are developed.
