What happens when neutron stars collide?

When stars collapse, they can leave behind incredibly dense but relatively small and cold remnants called neutron stars. If two stars collapse in close proximity, the leftover binary neutron stars spiral in and eventually collide, and the interface where the two stars begin merging becomes incredibly hot.

According to the researchers, neutrinos are created during the collision as neutrons in the stars smash into each other and are blasted apart into protons, electrons and neutrinos. What then happens in those first moments after a collision has been an open question in astrophysics. The researchers explained that the precise physical interactions that occur during the merger can impact the types of signals that could be observed on Earth from binary star mergers.

Funding from the U.S. National Science Foundation; the U.S. Department of Energy , Office of Science, Division of Nuclear Physics; the Deutsche Forschungsgemeinschaft; and the European Union Horizon 2020 and Europe Horizon initiatives supported this research. Simulations were performed on Bridges2, Expanse, Frontera and Perlmutter supercomputers.
