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 $M_{\odot }$ and radius around 11.16 $\mbox{km}$ , 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 $M_{\odot }$ .

具有普通和暗物质的致密星模型

我们研究由暗物质和普通物质形成的致密星，具有中子星物质和夸克星物质的属性。我们假设暗物质的状态方程与星系的旋转曲线和普通物质的色味锁定 (CFL) 分布一致。这是在广义相对论中弯曲的 Krori-Barua 时空几何中完成的。我们找到了暗物质混合致密物体的新精确解，最大质量为 2.67 $M_{\odot }$，半径约为 11.16 $\mbox{km}$，暗物质含量为 $52.40 \%$。通过改变暗物质比率，我们获得质量小于 2.67 $M_{\odot }$ 的暗致密恒星的质量。
