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…

Hybrid Quark Stars with Quark-Quark Phase Transitions
Zongcan Yang, Tianxiong Zeng, Yan Yan +3
We explore the possibility of phase transitions between different quark matter phases occurring within quark stars, giving rise to the hybrid quark stars (HybQSs). First, we obtain…

Bayesian inference of strangeon matter using the measurements of PSR J0437-4715 and GW190814
Wen-Li Yuan, Chun Huang, Chen Zhang +2
The observations of compact star inspirals from LIGO/Virgo combined with mass and radius measurements from NICER provide a valuable tool to study the highly uncertain equation of s…
