Vortex creep heating in neutron star cooling with direct Urca processes in heavy neutron stars
Yoonhak Nam, Kazuyuki Sekizawa
Old, thermally bright neutron stars imply internal heating at late times. Among candidate mechanisms, vortex creep heating (VCH) provides a robust link between spin-down and fricti…

Vortex Creep Heating in Neutron Star Cooling: New Insights into Thermal Evolution of Heavy Neutron Stars
Yoonhak Nam, Kazuyuki Sekizawa
Neutron stars provide unique laboratories for probing physics of dense nuclear matter under extreme conditions. Their thermal and luminosity evolution reflects key internal propert…
