Resum

In this talk, I will summarise our understanding of how observations can teach us about nucleon superfluidity at the extreme densities present in a neutron star's core. I will discuss the theory behind these systems, introducing the main ideas from nuclear physics and laboratory superfluids, and show how observations are beginning to constrain the theory in a useful way. The examples will involve the observed real-time cooling of the young neutron star in Cassiopeia A and the enigmatic glitches seen in many young radio pulsars. I will conclude by describing other settings where superfluidity is likely to play an important role.
