Impacts of dark matter on the curvature of the neutron star

Abstract

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