How do neutron stars create metals

WebThe star starts fusing helium to carbon, like lower-mass stars. But then, when the core runs out of helium, it shrinks, heats up, and starts converting its carbon into neon, which releases energy. This process continues as the star converts neon into oxygen, oxygen into silicon, and finally silicon into iron. WebFeb 1, 2024 · Neutron-star mergers and dying low-mass stars do not make heavy elements in equal proportions . Most xenon is produced in neutron-star mergers, whereas lead is primarily from low-mass stars. In the r-process, neutron captures proceed more rapidly than radioactive decay.
