Scientific paper
Consideration is given to the physical and astronomical conditions which are required for realizing the possibility of the generation of gamma-ray bursts for 'classical' and recurrent sources of gamma-ray bursts. It is shown that magnetodipole radiation of neutron stars which rotate with periods greater than 100 ms cannot evaporate a comet flying by at a distance of the order of the light cylinder radius. A physical model of switched-off pulsars is used to show that during the flyby of the comet in the magnetosphere of a neutron star, cosmic gamma-ray bursts can be generated. A new model of the Oort cloud, which is based on Comet Halley observations, agrees well with the observational data on recurrent bursts.
