The aim of this work is the study of hybrid stars interiors from the equations of state describing the matter composing them. We used modern hadronic equations of state to describe the matter in the outer core of these stars. The quark phase is modeled by an extended version of the Field Correlator Method, in which vector interactions among quarks and color superconductivity are included. We analyze the effect of these two contributions on the mass-radius relationship and tidal deformability. This is a relevant quantity for neutron stars after the GW170817 event, allowing to impose additional constraints to the equation of state of these compact objetcs.
