Аннотация:The evolution of the two recently discovered binary systems PSR B1259-63 and PSR J0045-7319 is calculated, based on an evolutionary scenario that predicts the existence of systems containing a radio pulsar and a massive optical star. Possible evolutionary tracks leading to the formation of such systems are presented. In order to explain the extremely high eccentricities of these systems, it is necessary to take into account the additional kick velocity of the neutron star, due to the anisotropy of the collapse during the supernova explosion. The resulting evolutionary tracks show the possible future fate of these unique binary systems.
