Neutron stars are known that have rotation periods from about 1.4 ms to 30 s. The neutron star's density also gives it very high surface gravity, with typical values ranging from 10 12 to 10 13 m/s 2 (more than 10 11 times that of Earth). [21]
Neutron stars are the collapsed cores of supergiant stars. [1] They are created as a result of supernovas and gravitational collapse, [2] and are the second-smallest and densest class of stellar objects. [3] In the cores of these stars, protons and electrons combine to form neutrons. [2] Neutron stars can be classified as pulsars if they are ...

Scientists have finally identified the progeny of that supernova - an enormously dense object called a neutron star. Two instruments on the James Webb Space Telescope (JWST) that observed the ...
Astronomers have found evidence that a neutron star exists at the centre of the only exploding star – supernova – visible to the naked eye in the last 400 years, solving a 30-year-old mystery.
The main trait that sets magnetars apart from other neutron stars is a magnetic field 1,000 to 10,000 times stronger than an ordinary neutron star's magnetism and a trillion times that of the sun.
For a typical neutron star of 1.4 solar masses (M ☉) and 12 km radius, the nuclear pasta layer in the crust can be about 100 m thick and have a mass of about 0.01 M ☉. In terms of mass, this is a significant portion of the crust of a neutron star. [9] [10]
The most massive type of degenerate star is the neutron star. See Most massive neutron star for this recordholder. [NB 4] Most massive neutron star PSR J0740+6620: 2019 2.14 M Sun: Several candidates exist which have a higher mass, however their mass has been measured by less precise methods and as such their mass value is regarded as less ...
