在引力被很好地理解之前,中子星的最大质量能排除致密恒星物质的任何状态方程吗?

Can the maximum mass of neutron stars rule out any equation of state of dense stellar matter before gravity is well understood?

摘要:

可能没有!作为一个例子,使用与现有的地球核实验室实验一致的软EOS,对含有夸克核的混合中子星进行了MIT袋模型描述,使用合理的参数,我们表明,最近发现的中子星最大质量PSR J1614-2230的新持有者$1.97\pm0.04M_{\odot}$可以很好地描述,通过纳入汤川引力校正,这与中子-质子和中子-铅散射以及反质子原子的光谱学。

英文摘要:

Probably No! As an example, using soft EOSs consistent with existing terrestrial nuclear laboratory experiments for hybrid neutron stars containing a quark core described with MIT bag model using reasonable parameters, we show that the recently discovered new holder of neutron star maximum mass PSR J1614-2230 of $1.97\pm0.04M_{\odot}$ can be well described by incorporating a Yukawa gravitational correction that is consistent with existing constraints from neutron-proton and neutron-lead scatterings as well as the spectroscopy of antiproton atoms.
