Helium core charge
WebIn the most direct continuation, two helium-3 nuclei (produced as indicated above) form one helium-4 nucleus ( 4 He, alpha particle) with the release of two protons, The path that produces the most energetic neutrinos uses a helium-4 nucleus as a catalyst and cycles through beryllium and boron isotopes at intermediate states. Web29 okt. 2024 · As the main sequence star glows, hydrogen in its core is converted into helium by nuclear fusion. When the hydrogen supply in the core begins to run out, and the star is no longer generating heat by nuclear fusion, the core becomes unstable and contracts. What happens during the protostar stage?
