Primordial black holes as a tool to probe strange quark stars

Huang, Yongfeng

Primordial black holes of planetary masses may be captured by compact stars such as neutron stars and strange quark stars. Such a capture may lead to an inspiral process and can be detected through gravitational-wave signals. In this talk, we will present our recent study on the postcapture inspiral process. It is found that the gravitational wave signals are different for a neutron star capturing event and a strange quark star capturing event. As a result, primordial black holes could be potentially used as a tool to probe the internal composition of pulsars.
