On the astronomical nature of the sources of gamma-ray bursts

The isotropy and log N/log S distribution of localized gamma-ray bursts are shown to indicate that their sources belong to the extended galactic corona. Bursts are supposed to be generated by old neutron stars with age < 109 yr excited by strong starquakes. The radiated energy is estimated to be...

Description
Summary:The isotropy and log N/log S distribution of localized gamma-ray bursts are shown to indicate that their sources belong to the extended galactic corona. Bursts are supposed to be generated by old neutron stars with age < 109 yr excited by strong starquakes. The radiated energy is estimated to be about 1042 erg per event. The nearest sources are at a distance of about 5 kpc. Practically all outbursts emitted inside the corona are detectable with available instruments. The anisotropy of the distribution of gamma-ray bursts on the sky may be well-pronounced only for the most powerful events. The identification of GRB 790305 with the SN remnant N49 in the Large Magellanic Cloud strongly confirms our conclusion.
