What is stellar nucleosynthesis ?
Stellar nucleosynthesis is a process involving nuclear reactions in which new atomic nuclei are synthesized from existing nuclei or nucleons. The first stage of nucleosynthesis occurred in the hot early universe, producing H, He, and trace amounts of Li-7 (primordial nucleosynthesis). In today's universe, nucleosynthesis takes place as follows.
(1) thermonuclear reaction and explosion inside the star (nucleus formation up to the Fe peak), (2) neutron capture and explosion inside the star (nucleus formation above the Fe peak), (3) stars Spallation reactions in interstitial matter, where light nuclei (Li, Be, and B) arise from the fragmentation of heavy nuclei (C, N, and O).
