WebHelium fusion in the Sun begins with a helium flash, or the release of a large amount of energy into the core of the star that kick-starts the helium fusion process. Specifically, helium flashes occur when degeneracy pressure increases the star’s temperature, causing the star’s helium fusion rate to rise extremely quickly. 10. WebJan 7, 2024 · I understand that for low-mass stars the helium flash occurs due to their degenerate helium cores. Thus the answer to this question is probably that more massive stars do not have a degenerate core, but I do not understand why they wouldn't.

Webthe Helium-burning reaction is explosive: a large amount of the Helium fuses to Carbon in a few seconds. This is called the Helium Flash, but it is not observable, since the photons produced in the explosion are trapped in the Hydrogen layers. The flash does not last long, since it quickly gets hot enough the gas returns to the ideal gas state.
