The "helium flash" occurs at what stage in stellar evolution?

Question

Quizplus · Accepted Answer

The helium flash occurs during the red giant stage in the evolution of a low-mass star. This is when the core of the star becomes hot enough to trigger fusion of helium into carbon. The flash occurs when the rate of fusion suddenly increases, releasing a large amount of energy and causing the star to briefly increase in luminosity. The "helium flash" occurs during the red giant phase of stellar evolution, when the core temperature and pressure become high enough to ignite helium fusion. This results in a sudden release of energy, but the outer layers of the star are not affected.
