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 ...
The neutron star equation of state encodes information about the structure of a neutron star and thus tells us how matter behaves at the extreme densities found inside neutron stars. Constraints on the neutron star equation of state would then provide constraints on how the strong force of the standard model works, which would have profound ...

Cross-section of neutron star. Here, the core has neutrons or neutron-degenerate matter and quark matter.. Neutronium is used in popular physics literature [1] [2] to refer to the material present in the cores of neutron stars (stars which are too massive to be supported by electron degeneracy pressure and which collapse into a denser phase of matter).
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 ...
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.
With Supernova 1987A, the star's size and the neutrino burst's duration had suggested the remnant would be a neutron star, but this had not been confirmed through direct evidence.
Not naturally occurring outside of neutron stars, but trace amounts are created in the detonation of nucleonic weapons. Horonium Star Trek (Introduced in Those Old Scientists.) Rare material, used as a component in constructing the NX-01 Enterprise, and as a fuel for a time portal on Krulmuth-B. Ice-nine Cat's Cradle
