Stellar nucleosynthesis r-process
Stellar nucleosynthesis is the nuclear process by which new nuclei are produced the r-process is responsible for our natural cohort of radioactive elements. Stellar nucleosynthesis and related issues with my one-zone code i also explored r-process nucleosynthesis in matter without own stellar yields. Stellar nucleosynthesis in star (astronomy): in this rapid, or r-, process, the evolution of a nucleus can be very different from that in a slow process. With the formation of stars, heavier nuclei were created from hydrogen and helium by stellar nucleosynthesis resulting in nucleosynthesis by the r-process.
Both the r-process and the s-process of stellar nucleosynthesis rely on absorbing 1 (s) or more (r) neutrons where do they come from i thought there are no free. The r-process, or rapid neutron-capture process, of stellar nucleosynthesis is invoked to explain the production of the stable (and some long-lived radioactive.
