  2. Nuclear fusion - Wikipedia

    en.wikipedia.org/wiki/Nuclear_fusion

    Nuclear fusion is the process that powers active or main-sequence stars and other high-magnitude stars, where large amounts of energy are released. A nuclear fusion process that produces atomic nuclei lighter than iron-56 or nickel-62 will generally release energy.

  3. Carbon-burning process - Wikipedia

    en.wikipedia.org/wiki/Carbon-burning_process

    Fusion processes are very sensitive to temperature so the star can produce more energy to retain hydrostatic equilibrium, at the cost of burning through successive nuclear fuels ever more rapidly. Fusion produces less energy per unit mass as the fuel nuclei get heavier, and the core of the star contracts and heats up when switching from one ...

    Advances in the potential energy source may not be about electricity, at least at first.

  5. Supernova nucleosynthesis - Wikipedia

    en.wikipedia.org/wiki/Supernova_nucleosynthesis

    Supernova nucleosynthesis is the nucleosynthesis of chemical elements in supernova explosions.. In sufficiently massive stars, the nucleosynthesis by fusion of lighter elements into heavier ones occurs during sequential hydrostatic burning processes called helium burning, carbon burning, oxygen burning, and silicon burning, in which the byproducts of one nuclear fuel become, after ...

    Since nuclear fusion produces no planet-warming greenhouse gas emissions, news outlets referred to fusion as “the ‘holy grail' of carbon-free, clean energy” and asserted as fact that ...

  7. Why is There New Interest in Fusion Energy? - AOL

    Ben Levitt is the director of research and development at Zap Energy. Scientists say nuclear fusion is very different than nuclear fission, which powers hundreds of power plants across the world.

  8. Helium flash - Wikipedia

    en.wikipedia.org/wiki/Helium_flash

    In the case of normal low-mass stars, the vast energy release causes much of the core to come out of degeneracy, allowing it to thermally expand. This consumes most of the total energy released by the helium flash, [2] and any left-over energy is absorbed into the star's upper layers. Thus the helium flash is mostly undetectable by observation ...

  9. Sun - Wikipedia

    en.wikipedia.org/wiki/Sun

    The Sun is the star at the center of the Solar System.It is a massive, nearly perfect sphere of hot plasma, heated to incandescence by nuclear fusion reactions in its core, radiating the energy from its surface mainly as visible light and infrared radiation with 10% at ultraviolet energies.
