Strange quark stars within proper time regularized (2+1)-flavor NJL model
Cheng-Ming Li, Shu-Yu Zuo, Yan Yan +4
In this work we use the equation of state (EOS) of (2+1)-flavor Nambu-Jona-Lasinio (NJL) model to study the structure of the strange quark star. With a new free parameter , the…
Exploring hybrid equation of state with constraints from tidal deformability of GW170817
Qing-wu Wang, Chao Shi, Yan Yan +1
With a interpolation method on the P- plane, a hybrid equation of state is explored. The quark phase is described by our newly developed self-consistent two-flavor NambuJona-…
Do the current astronomical observations exclude the existence of non-strange quark stars?
Tong Zhao, Wei Zheng, Fei Wang +4
As is pointed out in a recent work (Phys. Rev. Lett. 120, 222001), quark matter may not be strange. Inspired by this argument, we use a new self-consistent mean field approximation…
Constraints on the hybrid equation of state with a crossover hadron-quark phase transition in the light of GW170817
Cheng-Ming Li, Yan Yan, Jin-Jun Geng +2
In this paper, we use the recent updated source properties of GW170817 to constrain the hybrid equation of state (EOS) constructed by a three-window modeling between the hadronic E…
Studies of the structure of massive hybrid stars within a modified NJL model
Cheng-Ming Li, Jin-Li Zhang, Yan Yan +2
In this paper, we use the equation of state based on a modification of 2+1 flavors Nambu-Jona- Lasinio (NJL) model to study the quark matter of hybrid stars. For comparison, we uti…
