Gamma-ray bursts from the accretion of solid bodies onto high-velocity galactic neutron stars

We propose a simple model for the gamma-ray bursts based on high-velocity Galactic neutron stars that have accretion disks. The latter are formed from a mixture of material from the supernova shell and that ablated from a pre-supernova binary companion. Accretion onto the neutron star from this disk when the disk is still largely gaseous may result in a soft gamma-ray repeater phase. Much later, after the neutron star has moved away from its birthplace, solid bodies form in the disk, and some are perturbed into hitting the neutron star to create gamma-ray bursts. This model makes several predictions that are consistent with the observations. The observed combination of a high degree of isotropy on the sky coupled with the observed value of [l angle][ital V]/[ital V][sub [ital max]][r angle] is not, at first glance, predicted, but is not impossible to attain in our model.
