Title: Large-scale superfluidity in neutron stars
Abstract:

The majority of known isolated neutron stars is observed as pulsars, allowing the precise determination of their spin frequency over time. In the long-term, pulsars spin down due to rotational energy losses to their environment; however many of them — and especially the younger ones — occasionally display abrupt spin-up events known as glitches. The relaxation of pulsar rotation following the spin-up perturbation is very slow, a direct evidence that the neutrons in the stellar interior are in a superfluid state. I will review the phenomenology of glitches and discuss how observations combine with the latest theoretical models of neutron star internal dynamics to provide insights into dense matter physics.
