Neutron star merger - Wikipedia
A neutron star merger is the stellar collision of neutron stars. When two neutron stars fall into mutual orbit, they gradually spiral inward due to the loss of energy emitted as gravitational radiation. [1] When they finally meet, their merger leads to the formation of either a more massive neutron star, or—if the mass of the remnant exceeds ...
Neutron star collisions are a “goldmine” of heavy ... - MIT News
2021年10月25日 · New research suggests binary neutron stars are a likely cosmic source for the gold, platinum, and other heavy metals we see today. Most elements lighter than iron are forged in the cores of stars. A star’s white-hot center fuels the fusion of protons, squeezing them together to build progressively heavier elements.
