Neutrons weigh more, and the degeneracy pressure is different How were Neutron stars discovered? Jocelyn noticed very regular pulses of radio emission. The pulses were coming from a spinning neutron star—a pulsar. How were Neutron stars discovered? Observations of pulsars (pulsing Neutron stars)...
