Charged particles are trapped along the field lines. This region is called the light cylinder . Relativistic electrons in a strong magnetic field result in a beamed synchrotron emission. Pulsar Evolution Figure Chandra image of the Crab nebula. Figure Evolution of pulsar and the pulsar death line.
Pulsars radiate away their rotational energy.
Neutron Star Masses Figure Pulse timing orbit of accreting pulsar, SMC X-1. Pulsars in binaries allow us to estimate their masses via pulse timing orbits. Figure Masses of neutron stars. Neutron stars are supported by the neutron degenerate pressure . However, uncertainties remain because there is little laboratory data on the behaviors of nucleons under such extreme circumstances.
