Query: Impacts of dark matter on the curvature of the neutron star   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.
