What process takes place inside of stars?

Answer 1

Nuclear reactions produce the energy of the stars. Older stars undergo the triple-alpha process, while massive stars undergo the carbon cycle fusion and the Sun undergoes proton-proton fusion.Ê

Answer 2

Nuclear Fusion takes place inside stars. The intense pressure and heat energy inside the star fuses hydrogen fuel into helium at the core. This releases energy according to Einstein's formula, E=mc^2. Most main sequence stars, or the main period of a star's life, is made up of converting hydrogen to helium. Once this is done, the star becomes a giant and has to fuse helium into heavier elements and so on until it has no more energy to fuse heavier elements.

Answer 3

The main process taking place is nuclear fusion.
