  Neutrino emissivities due to direct Urca processes of several spin-one
color-superconducting phases of dense quark matter are calculated. In
particular, the role of anisotropies and nodes of the gap functions is
analyzed. Results for the specific heat as well as for the cooling rates of the
color-spin-locked, planar, polar, and {\it A} phases are presented and
consequences for the physics of neutron stars are briefly discussed.
Furthermore, it is shown that the {\em A} phase exhibits a helicity order,
giving rise to a reflection asymmetry in the neutrino emissivity.
