Giant X-Ray Source in Cygnus (Cygnus Superbubble) as a Remnant of a Peculiar Supernova

摘要

The analytic solution of equations for the evolution of supernova remnants in the radiative phase is found. It shows that the X-ray source Cygnus Superbubble might be formed by an explosion with the energy release 10 exp 52 -10 exp 53 erg. The analysis of the light curve of SN 1961 shows that this supernova in the result of an explosion with energy about 2x10 exp 52 erg in a supermassive star with the mass of order 10 exp 3 M * where M* is the solar mass. An evolutionary sequence for the formation of giant shell sources is suggested: presupernova - an object of the type R136a, supernova - an explosion of the type SN 1961 and the supernova remnant - a source of the type Cygnus Superbubble.
