The effect of color superconductivity on the cooling of quark stars and neutron stars with large quark cores is investigated. Various known and new quark-neutrino processes are studied. As a result, stars being in the color flavor locked (CFL) color superconducting phase cool down extremely fast. Quark stars with no crust cool down too rapidly in disagreement with X-ray data. The cooling of stars being in the N_f =2 color superconducting (2SC) phase with a crust is compatible with existing X-ray data. Also the cooling history of stars with hypothetic pion condensate nuclei and a crust does not contradict the data.

  1. Neutrino absorption in two-flavor color-superconducting quark matter

    nucl-th 2025-09 conditional novelty 7.0

    In 2SC quark matter, neutrino absorption is dominated by strange-quark capture at low temperature, and a degenerate neutrino gas at electron lepton fraction 0.1 has a mean free path of meters or less.
