Scientific paper

We have calculated the evolution of neutron stars surrounded by a supernova fallback disk, with an improved estimate of the torque exerted by the disk and the time dependence of the mass transfer rate. We show that, for reasonable distributions of its free parameters, the disk model is unable to produce any anomalous X-ray pulsars as observed-the influence of the fallback disk on neutron star evolution was overestimated. Based on the calculated results, we also critically comment on the fossil disk model proposed recently for young radio pulsars.
