Abstract

We study compact stars formed by dark and ordinary matter, with attributes of both neutron star matter and quark star matter. We assume an equation of state for dark matter which is consistent with the rotational curves of galaxies and for color-flavor-locked (CFL) distributions for ordinary matter. This is done in the curved Krori-Barua spacetime geometry in general relativity. We find new exact solutions of dark matter admixed compact objects, with maximum mass 2.67 M and radius around 11.16 km, with 52.40% of dark matter content. By varying the dark matter ratio, we obtain the masses of dark compact stars with masses less than 2.67 M .
