摘要:

利用刚性和柔性相对论平均场状态方程研究了暗物质对中子星曲率的影响。计算了NS的曲率随重子密度的变化。此外,它被发现,不同的曲率的径向变化显着影响的存在下,内部的NS DM。DM的影响不太明显的最大NS质量的紧凑性,但仍然显着。NS表面曲率被发现是更显着的大质量恒星。随着DM动量的增加,NS的结合能变为正值,使系统不稳定。

英文摘要:

The effects of dark matter (DM) on the curvatures of the neutron star (NS) are examined by using the stiff and soft relativistic mean-field equation of states. The curvatures of the NSs are calculated with the variation of baryon density. Also, it is found that the radial variation of the different curvatures significantly affected by the presence of DM inside the NS. The effects of DM are less pronounced on the compactness of the maximum NS mass, but still significant. The NS surface curvature is found to be more remarkable for the massive star. The binding energy of the NSs become positive with the increasing DM momentum and makes the system unstable.
