Anisotropic quark stars in energy-momentum squared gravity with an interacting quark equation of state
Abstract
We investigate anisotropic quark stars within the context of energy-momentum squared gravity (EMSG), assuming the internal composition consists of homogeneous, charge-neutral 3-flavor interacting quark matter with O(ms4) corrections. We performed numerical calculations of the equation of state (EoS) and the modified Tolman-Oppenheimer-Volkoff (TOV) structure equation. Additionally, we discussed the impact of the GB coupling parameter α on the mass-radius relationship. Furthermore, we compared our results with astronomical observational data. Our research offers a new perspective, proposing that in EMSG, accounting for anisotropy could lead to denser stars than in isotropic scenarios.
