Stellar nucleosynthesis is the nuclear process by which new nuclei are produced it occurs in stars during stellar evolution it is responsible for the galactic abundances of elements from carbon to iron. Here we will concentrate our attention in the nucleosynthesis of the light elements the extremely high temperatures of the early moments of the universe did not allow nuclei to exist at these temperatures, quarks had too much energy to be confined in protons and neutrons (the nuclear wall chart.
