νν¯-Pair synchrotron emission in neutron-star matter based on a relativistic quantum approach
We study the νν¯-pair synchrotron emission from electrons and protons in a relativistic quantum approach. This process occurs only in the presence of a strong magnetic field, and it is considered to be one of effective processes for neutron star cooling. In this work we calculate the luminosity of t...
