THE CONVERSION FROM NEUTRON-STARS TO STRANGE STARS AND ITS IMPLICATIONS

The conversion from neutron stars with different equation of states (E OSs) for neutron matter into strange stars with different EOSs for str ange quark matter has been studied in a general relativistic numerical calculation in this paper. For hot neutron stars, their conversion ma y lead to great variations in their rotation periods, of which the mag nitude would be greatly dependent upon the EOS for neutron matter, and of which the timescale would be greatly determined by the EOS for str ange matter. This phenomenon appears as giant glitches, which might pr ovide a probe of EOSs far both neutron matter and strange matter. But for cold neutron stars, their conversion may result in a population of gamma-ray bursts.
