Nature of the X-ray Source in Supernova Remnant RCW103
Authors:Sergei B Popov
Institution:(1) Sternberg Astronomical Institute, Moscow, Russia
Abstract:I discuss the nature of the compact X-ray source in the center of the supernova remnant RCW 103. Several models, based on the accretion onto a compact object are briefly discussed. I show that it is more likely that the central X-ray source is an accreting neutron star than an accreting black hole. I also argue that models of a disrupted binary system consisting of an old accreting neutron star and a new one observed as a 69-ms pulsar are most favored. This revised version was published online in July 2006 with corrections to the Cover Date.
