Brown Dwarf
Helium is converted to carbon in the final stage of fusion in stars like the Sun, which are considered to be medium-sized stars. This happens during the triple-alpha process where three helium nuclei combine to form a carbon nucleus.
Comparing the mass of the final helium-4 atom with the masses of the four protons reveals that 0.007 or 0.7% of the mass of the original protons has been lost. This mass has been converted into energy, in the form of gamma rays and neutrinos released during each of the individual reactions. The total energy yield of one whole chain is {{val|26.73|u=MeV}}.
the fusion of 4 hydrogen atoms to form 1 helium atom. Fusion of light atoms results in new energy, just as the breaking apart (fission) of heavy atoms does. It happens that iron is the mid-point (i.e. the atom with the least binding energy).
Stellar nebula: a cloud of gas and dust in space. Protostar: a young star still forming through gravitational collapse. Main-sequence star: stable fusion of hydrogen into helium in the star's core. Red giant: expansion of the star as it runs out of hydrogen fuel. Helium fusion: fusion of helium atoms in the core. Planetary nebula: outer layers of the star expelled into space. White dwarf: the core left behind after the outer layers are ejected. Black dwarf: a cooled and dim white dwarf. Supernova or black hole: the final stage, depending on the mass of the star.
Nucleosynthesis occurs during various stages of a star's life, primarily during the main sequence and later during the red giant phase. In the main sequence, hydrogen is fused into helium in the star's core. As stars evolve into red giants, they can undergo further nucleosynthesis processes, such as the fusion of helium into heavier elements like carbon and oxygen. In the final stages of massive stars, nucleosynthesis can lead to the formation of even heavier elements during supernova explosions.

Helium fuses into carbon as the final stage in the life cycle of intermediate-mass stars, typically those with a mass between 0.8 to 8 times that of the Sun. This process occurs during the core helium burning phase when the star has exhausted its hydrogen fuel and evolved off the main sequence.

Carbon releases energy through fusion in stars, where lighter elements combine to form heavier elements. In fission, carbon can release energy when split into smaller fragments. However, natural carbon fission is not a common process and is predominantly observed in laboratories.

During the fusion process, mass is converted into energy through the combination of atomic nuclei to form a heavier nucleus. This process releases a large amount of energy in the form of electromagnetic radiation, such as gamma rays. The energy released is a result of the difference in mass between the initial nuclei and the final nucleus, as described by Einstein's famous equation, Emc2.

In the sun it is just protons, which are hydrogen nuclei. On earth experiments are using two isotopes of hydrogen, deuterium and tritium. These are still the same element, hydrogen, just two different isotopes.
The Omega Metroid.
The cores of stars, such as our sun, have high enough temperatures and pressures to enable fusion of hydrogen nuclei - it is very difficult to fuse these positively charged particle together without these conditions. The mass of the nuclei before fusion is greater than the final mass of the fused particles - some of the mass is converted directly into energy through Einsteins equation E=mc2. m represents the mass, which although very small, is multiplied by the speed of light squared (c2), which is a very large number.
78% of the Earth's atmosphere is Nitrogen. Another 21% is oxygen, and the final 1% are other gases found is small amounts such as carbon dioxide, helium and methane.
