Abstract

Gamma-ray bursts, short flashes of nonthermal radiation, may shed light on the structure and formation rate of neutron stars. At least one and possibly all gamma-ray bursts originate from neutron stars, and the study of the mechanisms for generating bursts may elucidate the internal structure of these stars and, hence, the properties of high-density matter. This report summarizes salient observations of gamma-ray bursts and considers whether there is more than one class of gamma-ray burster and in what ways other astronomical systems have observed properties that resemble gamma-ray bursts. It then examines physical constraints on neutron star models of gamma-ray bursters and explores a particular model in which crustal glitches in neutron stars produce gamma-ray bursts.
