Neutron Star Vortex Dynamics and Magnetic Field Decay: Implications for High Density Nuclear Matter
Stephen D. H. Hsu
Abstract
We investigate the effect of the density-dependent proton and neutron gaps on vortex dynamics in neutron stars. We argue that the persistence of neutron star magnetic fields on timescales of 109 y suggests a superconducting gap curve with local maximum at intermediate density. We discuss the implications for exotic core phenomena such as pion/kaon condensation or a transition to quark matter.
