Electron-capture supernovae (ECSNe) are stellar explosions that occur in stars with initial masses around 8–10 times that of the sun. These stars develop oxygen-neon-magnesium cores, which become ...
Artist’s impression of the different layers inside a massive neutron star, with the red circle representing a sizable quark-matter core. New theoretical analysis places the likelihood of massive ...
Collisions between up, down, and strange quarks can result in a form of matter that cannot decay to any other form. Physicists think that, in some circumstances, neutron stars may accrete dark matter ...
