Self-bound hybrid stars with strong phase transitions can relieve major compact star observation tensions
Chen Zhang, Juan M. Z. Pretel, Renxin Xu
Some recent pulsar observations cannot naturally fit into the conventional picture of neutron stars: the compact objects associated with HESS J1731-347 and XTE J1814-338 have too s…

Hybrid stars with large quark cores within the parity doublet model and modified NJL model
Wen-Li Yuan, Bikai Gao, Yan Yan +1
Using the parity doublet model (PDM) for hadronic matter and a modified Nambu-Jona-Lasinio (NJL) model for quark matter, we investigate the potential existence of two- and three-fl…

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…
