How do you define stellar nucleosynthesis
WebNov 3, 2024 · Stellar nucleosynthesis is the process by which elements are formed within stars. The star formation theory proposes that stars form due to the collapse of the dense regions of a molecular cloud. A protostar is a stellar core formed when the fragments of a collapsed molecular cloud contract. WebMost of H and He weren't made from stars, but rather by the Big Bang. You can get all the way to Fe by stellar nucleosynthesis, and up to U or Pu through explosive nucleosynthesis (supernovae). So the ultimate minimum is one supernova-like event, so my guess is that the very lowest possible number of stars our atoms come from is 1.

When the star explodes into supernovas, it releases all of its energy as a burst of light and radioactive particles. During this process, a star is thought to undergo nucleosynthesis, which is the result of its own collapse in on itself.
