  2. Nuclear fusion - Wikipedia

    en.wikipedia.org/wiki/Nuclear_fusion

    The Sun is a main-sequence star, and, as such, generates its energy by nuclear fusion of hydrogen nuclei into helium. In its core, the Sun fuses 620 million metric tons of hydrogen and makes 616 million metric tons of helium each second. The fusion of lighter elements in stars releases energy and the mass that always accompanies it.

    The Sun produces on the order of 1% of its energy from the CNO cycle. [27] [a] [28]: 357 [29] [b] The type of hydrogen fusion process that dominates in a star is determined by the temperature dependency differences between the two reactions.

    en.wikipedia.org/wiki/Proton–proton_chain

    At the Sun's core temperature of 15.5 million K the PP process is dominant. The PP process and the CNO process are equal at around 20 MK. [1] Scheme of the proton–proton branch I reaction. The proton–proton chain, also commonly referred to as the p–p chain, is one of two known sets of nuclear fusion reactions by which stars convert ...

    en.wikipedia.org/wiki/Sun

    Since the Sun formed, the main fusion process has involved fusing hydrogen into helium. Over the past 4.6 billion years, the amount of helium and its location within the Sun has gradually changed. The proportion of helium within the core has increased from about 24% to about 60% due to fusion, and some of the helium and heavy elements have ...

  9. Solar core - Wikipedia

    en.wikipedia.org/wiki/Solar_core

    Due to fusion, the composition of the solar plasma drops from 68 to 70% hydrogen by mass at the outer core, to 34% hydrogen at the center. [4] The core contains 34% of the Sun's mass, but only 3% of the Sun's volume, and it generates 99% of the fusion power of the Sun.
