Compact stars consisting of strange quark matter and strange matter with admissible dark matter are studied by solving the Tolman‐Oppenheimer‐Volkoff equations for two fluids interacting only by gravity, with the dark‐matter EoS obtained by means of galaxy rotation curves. The properties of these stars are explored by means of the modeling of their mass‐radius relations and gravitational redshifts.
