Strange magnetars admixed with fermionic dark matter

Abstract We discuss strange stars admixed with fermionic dark matter in the presence of a strong magnetic field using two-fluid Tolman-Oppenheimer-Volkov equations. describe quark MIT bag model and consider fields range ? 10 17 - 18 G. For matter, we cases free particles strongly self-interacting particles, fermion masses m = 5, 100, 500 GeV. effects on radii stars, as well its tidal deformability. Even though contribute to decreasing total mass star, they attenuate rate decrease maximum brought about by increasing fraction system. The most intensely affected observable, however, is deformability, variations 70%-90% for reasonable values or central energy density.
