Abstract

Observable properties of neutron stars are studied within a hadronic equation of state derived from the quark level. The effect of short-range repulsion is incorporated within the excluded volume framework. It is found that one can sustain neutron stars with masses as large as 2.2M even including hyperons in β equilibrium, while producing radii and tidal deformabilities consistent with current constraints.

冷中子星现象学的排除体积效应
在从夸克水平导出的强子状态方程中研究了中子星的可观测特性。短程斥力的影响被纳入了排除体积框架。研究发现,我们可以维持质量高达 2.2M⊙ 的中子星,甚至包括处于 β 平衡的超子,同时产生与当前约束相一致的半径和潮汐变形。
