The petit four of color-superconducting phases in proto-neutron star evolution
By modeling proto-neutron star evolution from hot, neutrino-trapped birth states to cold, neutrino-transparent final states using a color-superconducting equation of state, the study identifies four distinct core evolution scenarios and concludes that a stable color-superconducting phase can only persist in the final cold neutron star within a narrow, high-mass region.
