Abstract

We examine and develop the model of gamma ray bursts origin proposed by Shaviv and Dar (1996), according to which the strong gamma ray emission is produced by the interaction of the baryonic relativistic jet with the soft photon field in a dense stellar region. By the simulations of the burst profiles we show that these profiles are sensitive to the jet geometry. Also we derive and discuss the model restrictions based on the event rate.

Key words: Gamma ray bursts jets neutron stars
