论文摘要

使用多个多夸克相互作用通道研究了混合恒星的可能存在。 HADRONIC相由目前接受的核物质特性的状态方程(EOS)组成,夸克模型受到几个光中膜的真空性能的约束。分析了几个NS属性对不同夸克相互作用的依赖性。我们表明,来自中子星观测到的目前限制允许存在具有较大陌生含量和大夸克核的混合恒星。

The possible existence of hybrid stars is studied using several multi-quark interaction channels. The hadronic phase consists of an equation of state (EoS) with presently accepted nuclear matter properties and the quark model is constrained by the vacuum properties of several light mesons. The dependence of several NS properties on the different quark interactions is analyzed. We show that the present constraints from neutron star observations allow for the existence of hybrid stars with large strangeness content and large quark cores.
