The Elements Forged in Stars

submitted by jwray

1 decade 6 years 3 weeks ago

Over 99.9% of atoms heavier than Helium-4 were formed via nuclear fusion inside stars. Other natural sources include spontaneous fission, big bang nucleosynthesis, cosmic ray spallation, radioactive decay, photodisintigration, neutron/alpha absorption, and (theoretically, I may have just made this up) ejection of material from neutron stars.

It would be interesting to find out what chunks of material ejected from neutron stars would decay into, and what nuclides would be formed besides hydrogen. It could be the case that certain nuclides which are never formed in ordinary stars can be the product of neutron stars.
