Resumen
Due to the high density of neutron stars, there is still an open question on the complete structure of the inner core of compact object. It is a great challenge to propose a model describing the highly-dense matter of neutron stars since there are neither experimentally nor observationally adequate results. In theoretical physics, Quantum Chromodynamics (QCD) predicts that at high densities and low temperatures the inner core of neutron stars could be made of exotic quark matter in the color-flavor-locked (CFL) phase of color superconductivity. Regarding the equation-of-state, we predict the existence of electrically charged strange quark stars in the background of the modified theory of gravity f(R, T). In our discussion, we assume a linear relation between charge density and the fluid energy density, and also utilize the f(R, T) = R+2fiT model to numerically compute the generalized Tolman-Oppenheimer-Volkoff (TOV) structure equations. In order to compute the properties of quark stars, we discuss the mass-radius profile, the effect of the charge in the stellar interior, factor of compactness, and mass-central energy density relation for stellar stability. Finally, we provide a set of basic differences between the standard Einstein-Maxwell gravity and the modified f(R, T) gravity theory.
