Overview
Advanced view of Neutron Stars & Neutron Degeneracy
A neutron star is the compact remnant produced when a massive stellar core collapses to densities comparable to atomic nuclei. With roughly one to two solar masses compressed into a sphere only tens of kilometers across, neutron stars probe matter at densities unattainable in terrestrial laboratories.
Neutron stars test nuclear physics, general relativity, magnetic-field evolution, superfluidity, gravitational waves, and the origin of some heavy elements.

Pulsar timing measures neutron-star masses with great precision, X-ray observations constrain radii, gravitational waves from neutron-star mergers probe tidal deformability, and observed masses above two solar masses rule out many overly soft equations of state.
