X-ray Pulsars and the Search for the Supra-nuclear Equation of State

Sharon Morsink, Univ. of Alberta

Abstract:

Neutron stars are tiny stars with ultra-strong magnetic and gravitational fields and densities larger than nuclear. Their small size and large average densities allow them to spin at very rapid rates, with surface velocities that are a large fraction of the speed of light. In the last 10 years a new class of rapidly-rotating accreting X-ray pulsars has been discovered. I will explain why observations of this type of pulsar have the potential to constrain the properties of supra-nuclear density matter and will give an overview of recent observations and theoretical work on this problem.
