Interesting, thank you for the answer! I wonder what the neutron lifetime in this case is. There's already the discrepancy between beamline and "jar" lifetime experiments. If we could measure neutron decay in a neutron star, we'd probably have another point of discrepancy 😆

The lifetime will mostly depend on phase space and temperature, so two quantities a free neutron doesn't care about. But these processes are responsible for cooling neutron stars down so we try to measure it. I have computed the rate a few times but never converted the units haha I will check
