Neutron Star, rapidly spinning, extremely dense astronomical object. Neutron stars are composed primarily of neutrons, minute, neutrally charged particles that exist in the nuclei of atoms. A neutron star is created when the core of a supergiant star—a massive star that has evolved so that it burns heavy elements instead of hydrogen—has converted all of the material in its core to iron. At this stage, no further nuclear reactions can take place to liberate energy, and so the core collapses under the mutual gravitational attraction of its own matter.
