With central densities way above the density of atomic nuclei, neutron stars contain matter in one of the densest forms found in the universe. Depending of the density reached in the cores of neutron stars, they may contain stable phases of…
If quark matter exists in the cores of neutron stars, it is most likely color superconducting. Thus a phase transition from free to paired quark matter might occur during the first minute of proto-neutron star evolution. In this talk I…
