Stable hybrid stars with colour superconducting quark matter core
Description
The present knowledge of quantum chromodynamics at high density indicates that quark matter might be in color superconducting phases. Thus, hybrid stars might contain color superconducting quark matter (CSQM) core surrounded by nuclear mantle. The possible CSQM phases are the two-flavor color superconductor (2SC), colour flavour locked (CFL) phase, and crystalline color superconductor. We compute the equations of state (EOSs) which correspond to the nuclear matter at low densities and CSQM in the 2SC or CFL phase at high densities. The EOSs for CSQM are calculated within the NJL model for different values of coupling strengths for the scalar diquark and isoscaler vector terms. The EOS at intermediate densities are obtained using Maxwell construction. These EOSs are used to construct stable configurations of static and rotating hybrid stars
