Difference between quark stars and neutron stars in universal relations and their effect on gravitational wave

Gao, Duanyuan

We calculate f-mode frequency and tidal overlap of quark stars using full general relativity method. We find universal relation between the f-mode frequency of quark stars is different with which of neutron stars. We further calculated the impact of this resulting dynamical tidal effect on the gravitational wave signal, but we finds it's too small to be detected.
