Neutron Stars and Pulsars

Pulsars are super dense but there's no fusion going on inside of them so they don't glow in the typical wavelengths. Sometimes you can see x-rays from cracks on their surface but what we're interested in is the beam that they emit along their magnetic north and south poles. Not every neutron star is a pulsar and we do not understand very well both the source of the radiation. We think maybe it comes from a combination of the rotation of this object and the charged particles on the surface.
