What Is Helium Flash - At the height of the flash, the sun's core will very briefly equal the combined luminosity of all the stars in the milky way galaxy! Web for obvious reasons, astronomers call this the helium flash. As a result of the helium burn process, the star will lose mass as it cools and eventually becomes a red giant. After this, the star becomes stable and reduces its luminosity and size briefly. The star is now in the core helium fusion phase of its lifecycle. This is a sign that the star is about to die and is rapidly running out of hydrogen. Web the term “helium flash” refers to a phenomenon known as a helium flash. When gravitational pressure has raised the temperature of the dormant helium core to a temperature of about 100 million k, the helium nuclei. In roughly the time it takes to toast a bagel, the flash releases as much energy as our current sun generates in 200 million years. In stars with masses about twice the mass of the sun or less, fusion stops after the helium in the core has been exhausted.
