Nucleosynthesis :an important nuclear astrophysics phenomenon: stellar nucleosynthesis by tarun p.
Carbon is believed to stem from a process known as supernova nucleosynthesis.
Stellar nucleosynthesis is the process of nuclear reactions taking place in stars to build the nuclei of the heavier elements, which are then incorporated in other stars and planets when that star dies, so that the new stars formed now start off with these heavier elements, and even heavier elements can then be formed from them, and so on.

The formation of heavy elements aside fusion of barge nuclei in the interior of stars is called astral nucleosynthesis.
How is temperature related to the nucleosynthesis process?
The proton–proton chain reaction cycle is relatively insensitive to temperature; a 10% rise of temperature would increase energy production by this method by 46%, hence, this hydrogen fusion process can occur in up to a third of the star's radius and occupy half the star's mass.
Which is the first element formed in nucleosynthesis?
A few minutes afterwards, starting with only protons and neutrons, nuclei up to lithium and beryllium (both with mass number 7) were formed, but hardly any other elements.
When does nucleosynthesis take place in a star?
This is the process that occurs during most of a star's lifetime. After the hydrogen in the star's core is exhausted, the star can burn helium to form progressively heavier elements, carbon and oxygen and so on, until iron and nickel are formed. Up to this point the process releases energy.
What kind of chemical reactions occur in stellar nucleosynthesis?
Stellar nucleosynthesis is the creation (nucleosynthesis) of chemical elements by nuclear fusion reactions within stars. Stellar nucleosynthesis has occurred since the original creation of hydrogen, helium and lithium during the Big Bang.
