Explain the research method that led to the discovery of neutron stars, located hundreds or thousands of light-years away; Describe the features of a neutron star that allow it to be detected as a pulsar; List the observational evidence that links pulsars and neutron stars to supernovae
Some neutron stars emit beams of electromagnetic radiation that make them detectable as pulsars, and the discovery of pulsars by Jocelyn Bell Burnell and Antony Hewish in 1967 was the first observational suggestion that neutron stars exist.

Describe the features of a neutron star that allow it to be detected as a pulsar. List the observational evidence that links pulsars and neutron stars to supernovae.
The Discovery of Neutron Stars. In 1967, Jocelyn Bell, a research student at Cambridge University, was studying distant radio sources with a special detector that had been designed and built by her advisor Antony Hewish to find rapid variations in radio signals.
Neutron Stars: The History. 1932 Landau suggests the existence of giant nucleus stars. 1932 Chadwick discovers the neutron. 1934 Baade & Zwicky predict the existence of neutron stars (NSs) as the end products of supernovae.
More massive stars explode as supernovae, leaving neutron stars or black holes at the centers of the supernovae remnants. The elements that were created within the cores of the first stars were ejected into space where they intermingled with the surrounding interstellar medium.
The fusion of deuterium inside protostars determines the location of the stellar birthline in the Hertzsprung–Russell diagram. In the most massive protostars, ordinary hydrogen ignites while cloud infall is still occurring. Overview. Stellar Life Cycle. All stars are born through the gravitational collapse of diffuse, interstellar clouds.
