Course
This lecture will describe the extreme properties of neutron stars and their environments and will discuss some of the latest and more exciting results concerning these relativistic objects.
Outline
  1. The formation of neutron stars
  2. Neutron star and magnetar properties
  3. Neutron star interiors
  4. Pulsar and millisecond pulsar characteristics
  5. Pulsar wind nebulae
  6. High energy emission from pulsars and recent Fermi results

Context


Neutron stars have masses of around 1.4 solar masses and radii of 10-12 km. As a consequence, the matter inside these objects is extremely dense, and in some cases even denser than the matter in the nucleus of the atom. This makes neutron stars interesting from the point of view of particle physics, where exotic particles may exist in an environment that we can not recreate on Earth. Further, the super-conducting protons inside neutron stars, coupled with the extreme charactersitics of these objects result in huge magnetic fields and the acceleration of particles to relativistic speeds, creating very high energy emission.
