What is the main source of energy of a star as it grows in size to becomes a red giant?
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.
The sun burns helium to make what other gas?
The sun burns small amounts of helium and when combined with oxygen, the helium makes neon. The sun burns mostly hydrogen.
Why does an old main sequence star have more helium than a young main sequence star?
Because it is older. The main sequence stars are the ones that get their energy by converting hydrogen-1 to helium-4. An older star can be expected to have advanced further in this conversion. Note that this is on average; how fast a star uses up its fuel (converts hydrogen-1 into helium-4) depends a lot on its mass.
Which stage follows a main sequence star?
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.
What type of star would helium be converted to carbon as the final stage of fusion?
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.
What fuel burns in a main sequence star?
Hydrogen "burns" as it were, in "nuclear fusion" reactions to give helium and release energy.
What is the main characteristic of a sequence star?
The defining characteristic of a main sequence star burns hydrogen to helium in its core.
What assists the star to give its own heat and light?
because the star burns and fuses hydrogen and helium (like the sun) making heat an light

What are the characteristics of white stars?
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.
Does sun burns helium to make hydrogen?
no it has hydogen and helium but it makes heat and light
What happens after a helium flash?
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 element that burns as fuel in star?
The energy in stars comes from nuclear fusion. Hydrogen atoms are continually fused together to created helium and with it, massive amounts of energy.
