Initially, a star's core is heated by compression as a nebula collapses. Once fusion is up and going, the fusion itself provides the necessary heat.

What is the process by which stars burn brightly?
Stars get their energy from nuclear fusion - mainly, hydrogen to helium.Stars get their energy from nuclear fusion - mainly, hydrogen to helium.Stars get their energy from nuclear fusion - mainly, hydrogen to helium.Stars get their energy from nuclear fusion - mainly, hydrogen to helium.
Are stars nuclear energy?
Stars produce nuclear energy by fusion Stars form when contracting dust in a planetary nebula contract and get so hot that nuclear fusion occurs. It explodes, forming a porotostar. Nuclear fusion of hydrogen atoms combining to form helium atoms is what keeps the star glowing.
Stars get there energy from?
Stars generally get their energy from hydrogen. By far the most common source of energy from a star (like our sun) is the nuclear fusion of hydrogen atoms into helium. As long as there is enough hydrogen, and other elements, to support the nuclear fusion, the process will go on. Therefore, stars generally get their energy from large amounts of hydrogen which coalesced during the star formation and through gravity received enough mass (weight) to start the nuclear process.
When does hydrogen-helium fusion and helium-carbon fusion occur in stars like our sun?
When hydrogen stocks run out
What are stars made of and What reactions keeps them alive?
Stars in our Milky Way are composed of about 71% hydrogen and 27% helium (mass) Thermonuclear fusion is what keeps the stars "shining", but this process is actually what leads to the eventual death of the stars. and in depth article can be found at http:/en.wikipedia.org/wiki/Star
A star generates energy by?

What is a falled star?
Assuming that the question refers not to a falled (??) star but to a failed star, the answer is that it is a star that does not have enough mass for hydrogen fusion to be sustain. Such stars are also known as brown dwarf stars.Assuming that the question refers not to a falled (??) star but to a failed star, the answer is that it is a star that does not have enough mass for hydrogen fusion to be sustain.

Hydrogen bombs and stars both produce energy with nuclear?
Nuclear fusion.
What triggers nuclear fusion stars?
Fusion in stars are usually the result of gravity.Once a mass of hydrogen accumulates enough mass, the gravity of all that mass compresses the core of the star to the point that the hydrogen atoms there begin fusing into helium. The process then cascades outward, and the end result is a star.
What is the fuel that runs fusion in stars?
Initially it is hydrogen. When that is spent, stars move to fusion of helium. There are also other fusion processes which take place: which process depends on the stars' mass.

Stars produce energy by fusing hydrogen into what?
The products of hydrogen fusion are helium and energy.
