Macroscopic properties of the XTE J1814-338 as a dark matter admixed strange star

In this paper, I discuss the macroscopic properties of the ultracompact object XTE J1814-338, whose inferred mass and radius read M = 1.21 ± 0.05 M ⊙ and R = 7.0 ± 0.4 km as a dark matter-admixed strange star. By using the neutralino as WIMP dark matter with a fixed Fermi momentum, I calculated the...

Summary:In this paper, I discuss the macroscopic properties of the ultracompact object XTE J1814-338, whose inferred mass and radius read M = 1.21 ± 0.05 M ⊙ and R = 7.0 ± 0.4 km as a dark matter-admixed strange star. By using the neutralino as WIMP dark matter with a fixed Fermi momentum, I calculated the moment of inertia, the gravitational redshift, the dimensionless tidal parameter, and the total amount of dark matter for a 1.2 M ⊙ star. At the end, I study the role of the neutralino’s mass.
