WebDec 2, 2024 · The inverse process (neutron upscattering) can enhance the Hoyle state’s decay rate to the bound states of ¹²C, effectively increasing the overall triple-alpha reaction rate. WebThe triple-alpha process is highly dependent on carbon-12 and beryllium-8 having resonances with slightly more energy than helium-4. Based on known resonances, by …
WebApr 30, 2014 · Astronomers recognize two distinct episodes of nucleosynthesis, primordial (big bang), and stellar. Nucleosynthesis has been invoked to explain the chemical abundances found in the universe. I particularly discuss stellar nucleosynthesis, through the proton-proton chain, the CNO cycle, the triple alpha process, the r process and s process.

Carbon was not made in the Big Bang, but was produced later in larger stars via the triple-alpha process. The subsequent nucleosynthesis of heavier elements (Z ≥ 6, carbon and heavier elements) ...
It is thought that the primordial nucleons themselves were formed from the quark–gluon plasma around 13.8 billion years ago during the Big Bang as it cooled below two trillion degrees. A few minutes afterwards, starting with only protons and neutrons, nuclei up to lithium and beryllium (both with mass number 7) were formed, but hardly any other elements. Some boron may have been for…
