Probing strange stars with advanced gravitational wave detectors

When a neutron star is squeezed to huge densities, it can be converted to a strange star. Using the event/year rate of a neutron star-strange star binary system, we show that the operational phase of advanced gravitational wave detectors might show some evidence that such strange stars do exist. Moreover, we argue that such a system could be a plausible progenitor to GRB 051103 and GRB 070201. In the last run of the Laser Interferometer Gravitational-Wave Observatory (LIGO), no gravitational wave signal was found for these gamma-ray bursts, and a conclusive explanation for this needs to be found.
