摘要

本文研究了核质量对致密/中子星质量-半径关系的影响。除了质量外,核心的参数化还包括其半径和表面压力,这支持了外部的单组分标准模型(SM)物质。核心可以容纳具有未指定(或鲜为人知)状态方程或几种成分的SM物质,例如,由暗物质和/或镜像世界物质的混合物组成。这样,致密恒星的质量和半径的容许范围就可以大大扩大。

Masses of Compact (Neutron) Stars with Distinguished Cores
In this paper, the impact of core mass on the compact/neutron-star mass-radius relation is studied. Besides the mass, the core is parameterized by its radius and surface pressure, which supports the outside one-component Standard Model (SM) matter. The core may accommodate SM matter with unspecified (or poorly known) equation-of-state or several components, e.g., consisting of admixtures of Dark Matter and/or Mirror World matter etc. beyond the SM. Thus, the admissible range of masses and radii of compact stars can be considerably extended.
