Abstract

Neutron stars are famously steady rotators, but some occasionally undergo sudden changes in their spin frequency known as glitches. I will discuss the theoretical and observational considerations for the origin of glitches in the superfluid interior of neutron stars, and present the results of simulations which show how interacting superfluid vortices in a model of a neutron star can produce similar behaviour to glitches in pulsars.
