论文摘要
我们使用从MITER中的PSR J0030+0451的质量和半径测量来限制贝叶斯统计方法中夸克恒星状态的方程。由有限的Quark质量和/或超流量的三种类型的袋子模型用于用自绑的奇怪夸克物质组成的夸克星。 We find the $90\%$ posterior credible boundary around the most probable values of the quark star maximum mass is $M_{\rm TOV}=2.38_{-0.23}^{+0.26}\,M_{\odot}$, within the model flexibility of the finite quark mass, the quark pairing gap, and the perturbative contribution from the一个绿色交流。规范$ 1.4 \，m _ {\ odot} $ quark star的半径是$ r _ {\ rm 1.4} \ sim12.3 \，{\ rm km km} $，比基于中子星模型的结果小。
We constrain the equation of state of quark stars within the Bayesian statistical approach using the mass and radius measurements of PSR J0030+0451 from NICER. Three types of bag models, with and without non-zero finite quark mass and/or superfluidity, are employed for quark stars made up with self-bound strange quark matter. We find the $90\%$ posterior credible boundary around the most probable values of the quark star maximum mass is $M_{\rm TOV}=2.38_{-0.23}^{+0.26}\,M_{\odot}$, within the model flexibility of the finite quark mass, the quark pairing gap, and the perturbative contribution from the one-gluon exchange. The radius of a canonical $1.4\,M_{\odot}$ quark star is $R_{\rm 1.4}\sim12.3\,{\rm km}$, smaller than the results based on neutron star models.
