中子星能量密度的意义及中子星性质的普遍性

Significance of lower energy density region of neutron star and universalities among neutron star properties

Wasif Husain, Anthony W. Thomas

摘要:

在Hartle框架下,我们建立了旋转中子星和奇异星的模型,并进行了比较。研究了中子星内部低能量密度区和地壳区的意义,以及能量密度300 MeV/fm 3以上的奇异物质的存在对中子星性质的影响。我们证实了中子星的无量纲转动惯量与无量纲四极矩、无量纲潮汐形变与无量纲转动惯量、转动惯量参数与R/2 M等性质之间的普遍性。

英文摘要:

We have constructed and compared models of rotating neutron stars and strange stars, within the Hartle framework. The significance of the low energy density region and crust region inside the neutron star has been studied, along with how much the existence of strange matter above the energy density 300 MeV/fm3 can affect the neutron star properties. We have confirmed several universalities among the neutron star properties such as, dimensionless moment of inertia vs dimensionless quadrupole moment, dimensionless tidal deformability vs dimensionless moment of inertia and moment of inertia parameters vs R/2M.
