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
In 2003, Marta Burgay and colleagues discovered the first double neutron star system where both components are detectable as pulsars, PSR J0737−3039. [100] The discovery of this system allows a total of 5 different tests of general relativity, some of these with unprecedented precision.

1 Δεκ 2017 · In the discovery paper 1 we had considered these objects to be pulsating (vibrating) neutron stars; others wondered about rotating neutron stars. The issue was settled in mid-1968 when the...
4 Μαρ 2020 · Now, after decades of speculation, researchers are getting closer to solving the enigma, in part thanks to an instrument on the International Space Station called the Neutron Star Interior ...
The term “neutron star” as generally used today refers to a star with a mass M on the order of 1.5 solar masses (M ⊙), a radius R of ∼12 km, and a central density n c as high as 5 to 10 times the nuclear equilibrium density n 0 ≅ 0.16 fm –3 of neutrons and protons found in laboratory nuclei.
A special kind of neutron star, known as a pulsar, emits periodic—or repeating—bursts of radio waves, X-rays and gamma rays. The first pulsar was discovered in 1967 by Cambridge University researchers Jocelyn Bell Burnell and Anthony Hewish—though their existence had been predicted more than three decades earlier by Fritz Zwicky and others.
