At the endpoint of stellar evolution, pulsars are spinning extremely rapidly with periods ranging from milliseconds to seconds and delays of a few milliseconds per year at most, thus providing the most accurate clocks in the universe. Nevertheless, some pulsars exhibit sudden decreases of their spin period. Because it was the first observed pulsar to exhibit such “glitches”, Vela has become...

Cooling neutron stars may serve as natural laboratories of superdense matter in their interiors. We discuss current theories of neutron star cooling. We outline the main regulators of the cooling such as the equation of state, neutrino emission mechanisms, heat capacity and superfluidity in superdense stellar cores as well as the properties of heat-blanketing envelopes of neutron stars. Next...

I will review some key aspects of the physics of neutron star superfluidity and superconductivity, which play an important role in the phenomena of pulsar timing noise and rotational glitches. New results will be presented from quantum mechanical Gross-Pitaevskii simulations of vortex avalanches in a pinned, decelerating superfluid, which show the correlated nature of vortex motion during...
