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