23 Οκτ 2024 · The discovery of pulsars in 1967 provided the first evidence of the existence of neutron stars. Pulsars are neutron stars that emit pulses of radiation once per rotation. The radiation emitted is usually radio waves, but pulsars are also known to emit in optical, X-ray, and gamma-ray wavelengths.

Within minutes, these protons and neutrons combined into nuclei. As the universe continued to expand and cool, things began to happen more slowly. It took 380,000 years for electrons to be trapped in orbits around nuclei, forming the first atoms.
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.
1 Δεκ 2017 · We now believe pulsars are neutron stars (that is, neutron-rich stars) formed from the core of a massive star as it undergoes a supernova explosion at the end of its life.
