Abstract

In this work we determine the critical density values of the phase transition between the hadronic to the CFL superconducting quark matter. The Delta resonances and the complete spin-1/2 baryonic octet are considered in the hadronic phase and it is observed that the delta matter inclusion in baryonic phase modifies significantly the critical conditions for the phase transition. Also, we discuss the role of the color superconducting gap on the structure properties of a formed hybrid neutron stars.
