  In this poster 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 such as a neutron star or a black hole (isolated or binary), are
analyzed. 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 X-ray and radio pulsar are most favored.
