Neutron stars are the gravitational collapsed core of massive stars (9-10 solar masses) that have gone supernova. They are some of the densest objects in the universe only being surpassed by black holes. They generally have masses in the order of 1.5 solar masses compact into an area of just 12 kilometers. Currently the most massive neutron star that has been discovered is PSR J1748-2021B which has a mass of 2.5 solar masses. Below is a list of high-mass neutron stars.
