Equations of state and stability of color-superconducting quark matter cores in hybrid stars

Understand

The stable configurations of non-rotating and rotating hybrid stars composed of colour superconducting quark matter core are constructed using several equations of state (EOSs).

• We use a set of diverse EOSs for the nuclear matter which represents the low density phase.
• The EOSs at higher densities correspond to the quark matter in the colour superconducting phase and are computed within the NJL-like model for different values of the scalar diquark and vector current couplings strengths.
• The phase transition to the quark matter is computed by a Maxwell construction.
