论文摘要
我们通过改变袋子常数来研究状态（EOS）混合方程的恒星物质特性。我们为强子阶段使用有效的场理论相对论均值野外模型（E-RMF），最近报道了FSUGARNET，G3和IOPB-I参数集。还显示了NL3和NL3 $ {ωρ} $集的结果以进行比较。简单的MIT袋模型用于夸克相，以构建混合EOS。混合中子星质量和半径是通过与$ b^{1/4} $变化来计算的，以约束$ b^{1/4} $ values。发现$ b^{1/4} $ = 130-160 MEV适合在中子星中解释夸克物质。
We study the star matter properties for Hybrid equation of state (EoS) by varying the bag constant. We use the Effective-Field-Theory motivated Relativistic Mean-Field model (E-RMF) for hadron phase with recently reported FSUGarnet, G3 and IOPB-I parameter sets. The result of NL3 and NL3${ωρ}$ sets are also shown for comparison. The simple MIT Bag model is applied for the quark phase to construct the hybrid EoS. The hybrid neutron star mass and radius are calculated by varying with $B^{1/4}$ to constrain the $B^{1/4}$ values. It is found that $B^{1/4}$=130-160 MeV is suitable for explaining the quark matter in neutron stars.
