    "abstract": "If deconfined quark matter exists inside compact stars, the primary cooling\nmechanism is neutrino radiation via the direct Urca processes d-\u003eu+e+antinu_e\nand u+e-\u003ed+nu_e. Below a critical temperature, T_c, quark matter forms a colour\nsuperconductor, one possible manifestation of which is a condensate of \u003cud\u003e\nquark Cooper pairs in an electric-charge neutralising background of electrons.\nWe compute the neutrino emission rate from such a phase, including charged\npair-breaking and recombination effects, and find that on a material\ntemperature domain below T_c the pairing-induced suppression of the neutrino\nemission rate is not uniformly exponential. If gapless modes are present in the\ncondensed phase, the emissivity at low temperatures is moderately enhanced\nabove that of completely unpaired matter. The importance of charged current\npair-breaking processes for neutrino emission both in the fully gapped and\npartially gapped regimes is emphasised.",
