Nuclear fusion

The nuclear binding energy curve. The formation of nuclei with masses up to Iron-56 releases energy, while forming those that are heavier requires energy input. This is because the nuclei below Iron-56 have high binding energies, while the heavier ones have lower binding energies, as illustrated above.

The Sun is a main-sequence star, and thus generates its energy by nuclear fusion of hydrogen nuclei into helium. In its core, the Sun fuses 620 million metric tons of hydrogen each second.

Δmc2|, where Δm is the decrease in the total rest mass of particles.[1]

In nuclear physics, nuclear fusion is a nuclear reaction in which two or more atomic nuclei come very close and then collide at a very high speed and join to form a new nucleus. The mass of this new nucleus is slightly less than the sum of its constituents, by an amount known as the "binding energy". This is because the compound nucleus is a lower-energy system (a "more favourable" system energetically) than the two parent nuclei. The binding energy is released as photons (energy). This is the energy that is given off by a fusion process. Fusion is the process that powers active or "main sequence" stars, or other high magnitude stars.
