V. Thorsson et al., NEUTRINO EMISSION FROM DENSE MATTER CONTAINING MESON CONDENSATES, Physical review. D. Particles and fields, 52(6), 1995, pp. 3739-3741
We consider the rate at which energy is emitted by neutrinos from the
dense interior of neutron stars containing a Bose condensate of pions
or kaons. The rates obtained are larger, by a factor of 2, than those
found earlier, and are consistent with those found for the direct Urea
processes.
