WebAt some point, the helium core reaches a density and temperature at which the triple-alpha process starts to fuse helium into carbon. This reaction (as you may recall) is VERY sensitive to temperature: So, when the reactions begin, they produce energy, which raises the temperature of the helium core. WebOnce the core reaches a temperature of about 100 million Kelvin Helium fusion starts dramatically (Helium Flash) with high radiation pressure in the core. Here is where the Sun will reach 250 times it's current radius. When the Helium fusion stabilizes the radiation pressure at the cores decreases making the Sun's radius to shrink.
Web7 jul. 2024 · Fusion is the process that powers the sun and the stars. It is the reaction in which two atoms of hydrogen combine together, or fuse, to form an atom of helium. In …
