Neutrino luminosity of the bubble phase layer in a hot neutron star
Leinson L.B.
A new mechanism of neutrino emission is suggested for a newly born neutron star cooling. Nucleons emit neutrino-pairs due to collisions with bubbles which exist inside the spherical layer of stellar matter from half nuclear to nuclear density. During the earliest stages of the nascent neutron star cooling the pair luminosity of this somewhat thin spherical layer is of the order of 1053 ergs/s.
