论文摘要
通过使用状态的僵硬和柔软的相对论均值场方程，检查了暗物质（DM）对中子星（NS）曲率的影响。 NSS的曲率是通过Baryon密度变化计算的。同样，发现不同曲线的径向变化显着受到NS内DM的影响。 DM的影响对最大NS质量的紧凑性不太明显，但仍然显着。发现NS表面曲率对于巨大的恒星更为显着。 NS的结合能随着DM动量的增加而变得阳性，并使系统不稳定。
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.
