Description
Owing to the extreme densities, pressures and low (on the nuclear physics scale) temperatures of their interiors, neutron stars act as cosmic laboratories for superfluid dynamics. The theoretical motivation for this is well established and pulsar glitches – sudden spin-up events followed by a gradual relaxation – provide convincing observational support. Nevertheless, and despite about half a century of deliberation, we do not yet have robust theoretical models than can be directly tested against observations. In this talk, I will survey the problem and – at least try to – suggest ways that we may make progress.
