Scientific paper

A model of cosmic gamma-ray bursts is proposed, involving spherical accretion on compact objects from the stellar wind of a companion star. The gamma-bursts arise when occasional flares in the companion drive shocks in the wind, which then produce a short increase in the accretion rate on the compact object. In the interval between flares, the steady accretion from the wind leads to an X-ray source behavior compatible with that of observed galactic X-ray sources. The model is flexible enough to reproduce the large range of observed gamma-ray burst characteristics, including luminosities, timescales and approximate spectra. Specifically, it can explain the recently suggested possibility that Cygnus X-1 is responsible for some of the gamma-ray events, as well as the recently reported orbit-modulated absorption features.
