Abstract
We study the conversion of a neutron star to a strange star as a possible e nergy source for gamma-ray bursts. We use different recent models for the e quation of state of neutron star matter and strange quark matter. We show t hat the total amount of energy liberated in the conversion is in the range of (1-4) x 10(53) ergs (1 order of magnitude larger than previous estimates ) and is in agreement with the energy required to power gamma-ray burst sou rces at cosmological distances.
