Abstract

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 the νν¯-pairs emitted from neutron-star-matter with a magnetic field of about 10¹⁵ G. We find that the energy loss is much larger than that of the modified Urca process. The νν¯-pair emission processes in strong magnetic fields is expected to contribute significantly to the cooling of the magnetars.
