Scientific paper

Thirty-two gamma-ray bursts (GRBs) from the direction of the flare star AB Dor are analyzed in the framework of the hypothesis that there is a relation between cosmic GRBs and flare stars. The main aim of the analysis is to search for time correlations between the bursts. The probability that the bursts are random in time is 10^-3, which may provide evidence for the recurrent emission of GRBs by this flare star. This is one of the first identifications of a GRB source with a stellar object. The mean burst luminosity of the star in gamma-rays with energies greater than 20 keV is 3 x 10^34 erg s^-1.
