Scientific paper

An analytic solution is obtained for the evolution of a supernova remnant during the radiative-cooling phase. The Cygnus Superbubble X-ray source could have been formed by the explosion of a single supernova releasing an energy of 10 to the 52nd - to to the 53rd erg. Analysis of the light curve of the NGC 1058 supernova 1961v demonstrates that it represents an approximately 2 x 10 to the 52nd outburst of a supermassive (approximately 1000 solar masses) star. Giant shell sources may form an evolutionary sequence, exemplified by R136a as the presupernova, supernova 1961v, and the Superbubble as the remnant.
