Description
The neutron star in HESS J1731-347 is the hottest know isolated neutron star for its age (excluding magnetars). It is cooling mainly due to neutrino emission from its core, and this emission has to be inefficient because of the high observed temperature. This fact allows us to put constraints on other hypothetical cooling processes like axion emission in n-n bremsstrahlung processes and improve the constraint obtained from SN 1987A on the coupling of axion to neutrons.
