From 2018 to 2020, I visited the Institute for Theoretical Physics, Goethe University Frankfurt, for two years' joint training PhD program. My research interest mainly concentrates on the compact stars and their implicit consequence of observation. By implementing the upcoming 3rd gravitational wave detectors, I am exploring the possibility and availability to determine the state and properties of dense matter. 地点 Physics Building 552 (online)

Abstract:

The hypothesis that strange quark matter is the true ground state of matter has been investigated for almost four decades, but only a few works have explored the dynamics of binary systems of quark stars. In this talk, I will talk about our explorations of the binary quark star merger, including the gravitational wave emission, the impact of the magnetic field, the dynamic process of merger, the matter ejection, and its implication on the electromagnetic counterpart. Finally, I will also discuss the differences between binary quark star and binary neutron star mergers, and the possibility of distinguishing them through the gravitational wave observations.
