Scientific paper

A spherically symmetric hydrodynamic code is used to study the dynamical evolution and nonequilibrium X-ray emission of supernova remnants of type II supernovae. The interaction of the supernova ejecta with the dense circumstellar medium (CSM) is shown to lead to strong X-ray emission and to hardening of the X-ray spectrum (if electrons are not heated substantially at the collisionless shock front). After the blast shock breaks out of the CSM into the rarefied ambient medium, the X-ray spectrum is characterized by strong recombination lines and continua.
