Moment of Inertia and Tidal Deformability of a Quark Star in Eddington-inspired Born Infeld Theory

In this paper, we report our investigation on the moment of inertia and tidal deformation of a quark star in the Eddington-inspired Born Infeld gravity, which has κ and Λ_c as its parameters. Corresponding to the quark star matter, we use an equation of state (EoS) from either the MIT-Bag model or the CIDDM model. Eight different EoSs are used, four are from variations in the MIT-Bag model, and the rest are from variations in the CIDDM model. We find that the results from the four EoSs from the MIT-Bag model have more significant differences than the results from the CIDDM model. We also find that if we use the observed value of the cosmological constant Λ_c, it gives no significant difference compared to the standard case in general relativity (TOV GR). On the other hand, κ gives a significant difference compared to the TOV GR case.
