Abstract
The galactic model of gamma-ray bursts (GRBs) is based upon the observed production of soft gamma-ray repeaters (SGRs) in our galaxy and the consequences of a reasonable model to explain them. In this view GRBs are the long term result of the burn-out conditions of the SGRs in this and in other galaxies. A delay of ∼30 million years before GRBs are being actively produced can be understood as the time required for the ejected matter during the SGR phase to cool, condense, and form planetesimals that are eventually captured by the central neutron star. The amount of disk matter and the interaction between each GRB and the disk determine the rate of burst production and turn-off time of GRBs. The X-ray afterglow as well as optical emission is derived from X-ray fluorescence and ionization of previously ablated matter.
