All red giant stars will start helium fusion when their core is compressed.
The sun burns small amounts of helium and when combined with oxygen, the helium makes neon. The sun burns mostly hydrogen.
A main sequence star burns hydrogen to helium. Once a main sequence star exhausts all of the hydrogen, it begins to expand and burn helium causing if to become a red giant.
Stars convert hydrogen into helium over time.However, please note that they do so at very different rates; a massive star burns its fuel (hydrogen) much faster than a less massive star - so you can well have a massive star, which is only a few million years old, but which already burnt much of its fuel.
After the main sequence stage, a star like the sun will enter the red giant phase where its core contracts and the outer layers expand. This is followed by the helium fusion stage where the star burns helium in its core. Ultimately, the fate of a star depends on its mass, which determines if it will become a white dwarf, neutron star, or black hole.
Helium is converted into carbon during the final stage of fusion in a star called a red giant. This process occurs when helium fusion in the core of the star gives rise to carbon as the result of nuclear reactions.
Hydrogen "burns" as it were, in "nuclear fusion" reactions to give helium and release energy.
The defining characteristic of a main sequence star burns hydrogen to helium in its core.
because the star burns and fuses hydrogen and helium (like the sun) making heat an light

no it has hydogen and helium but it makes heat and light
It is the Post-Main sequence star that burns helium. They are considered giants, unlike our sun, which is a Yellow Dwarf. they are extremely hot and large.
Helium is converted into carbon during the final stage of fusion in a star called a red giant. This process occurs when helium fusion in the core of the star gives rise to carbon as the result of nuclear reactions.
The luminosity of a low mass star goes down after helium flash. The sudden onset of helium fusion stops core shrinkage and the low-mass star will become smaller, and less luminous than it was as a red giant.
The energy in stars comes from nuclear fusion. Hydrogen atoms are continually fused together to created helium and with it, massive amounts of energy.
