The Most Massive Neutron Stars Probably Have Cores of Quark Matter

When a star with several times the mass of the Sun dies in a supernova explosion, it ends up as a neutron star, compressing its protons and electrons into neutrons. But neutron stars have layers, and the most massive ones there might have a core made of an even denser material called "deconfined quark matter." A new supercomputer simulation predicts that the most massive neutron stars almost certainly have these quark-matter cores. The post The Most Massive Neutron Stars Probably Have Cores of Q...
