Figure 20: The radio pulsar equivalent of the Hertzsprung-Russell diagram - a
physical diagram indicating the nature and evolution of neutron stars. Each
dot represents a pulsar, stars represent pulsars associated with supernova
remnants, circles indicate pulsars in binary systems and ellipses indicate
pulsars in binary systems with eccentric orbits.
