Question on neutrino emission machanism in neutron star

[TuGmOS]

How many neutrino emission mechanism, that causes the cooling of star, are there in neutron star?

And How, what equation, to calculate the emissivity of each mechanism?

This is the best paper I've seen to date:

Neutrino Emission from Cooper Pairs and Minimal Cooling of Neutron Stars
The direct urca process is not very satisfactory, imo. This appears a better alternative.

There's a chapter in this paper regarding Neutrino Emission and Stellar Cooling with an overview of the various processes, pages 56-61-
