Subsolar-mass binary mergers of strange stars and neutron stars: gravitational waves and ejecta
Yong Gao, Ming-Zhe Han, Kenta Kiuchi +3
We present the first numerical-relativity simulations of subsolar-mass binary strange star (SS) mergers and compare with binary neutron star (NS) mergers across equations of state,…
Nonradial oscillations of stratified neutron stars with solid crusts: Mode characterization and tidal resonances in coalescing binaries
Yong Gao, Hao-Jui Kuan, Cheng-Jun Xia +2
Dynamical tides of neutron stars in the late stages of binary inspirals provide a viable probe into dense matter through gravitational waves, and potentially trigger electromagneti…
Convective stability analysis of massive neutron stars formed in binary mergers
Yong Gao, Kota Hayashi, Kenta Kiuchi +3
We perform fully general-relativistic hydrodynamics simulations of binary neutron star mergers over post-merger to investigate the dynamics of remnant massive neutron…
Difference between quark stars and neutron stars in universal relations and their effect on gravitational waves
Duanyuan Gao, Hao-Jui Kuan, Yurui Zhou +4
We calculate the -mode frequency and tidal overlap of quark stars using the full general relativity method. We verify the universal relations obtained from conventional neutron…
Dependence of postmerger properties on the thermal heating efficiency in neutron star mergers
Ming-Zhe Han, Yong Gao, Kenta Kiuchi +1
We systematically perform numerical-relativity simulations for equal-mass binary neutron star mergers for the models varying the thermal index with three different eq…
