Neutron stars as fundamental physics laboratories

With a mass of just over that of the Sun squeezed into the radius of a small city, neutron stars involve extreme physics that cannot be probed in terrestrial laboratories. Matter has been compressed beyond nuclear density and the bulk of the star is likely to be in a superfluid state. The star’s magnetic field (which may be immensely strong) is anchored in a superconducting core. We have many exciting ideas but we have to turn to astrophysical observations to test our predictions. This is a messy business, because neutron stars have a complex phenomenology and the different aspects we want to probe are not easily decoupled. In this talk, I will provide an overview of the problem, drawing on a range of observations - from radio to x-rays and gravitational waves. The aim is to summarise the current state of play and provide some hints of what we expect in the future.
