What does nucleosynthesis mean?
Which is the result of nucleosynthesis in a supernova?
The remains of their ejected mass form the planetary nebulae observable throughout our galaxy. Supernova nucleosynthesis within exploding stars by fusing carbon and oxygen is responsible for the abundances of elements between magnesium (atomic number 12) and nickel (atomic number 28).
What is the minimum temperature needed for nucleosynthesis?
Nucleosynthesis requires a high-speed collision, which can only be achieved with very high temperature. The minimum temperature required for the fusion of hydrogen is 5 million degrees. Elements with more protons in their nuclei require still higher temperatures. For instance, fusing carbon requires a temperature of about one billion degrees!
Where is helium released in the nucleosynthesis process?
The helium nucleus is released at the top-left step. Hydrogen fusion (nuclear fusion of four protons to form a helium-4 nucleus) is the dominant process that generates energy in the cores of main-sequence stars. It is also called "hydrogen burning", which should not be confused with the chemical combustion of hydrogen in an oxidizing atmosphere.
How are chemical elements created in stellar nucleosynthesis?
Process by which the natural abundances of the chemical elements within stars change due to nuclear fusion reactions. Stellar nucleosynthesis is the creation (nucleosynthesis) of chemical elements by nuclear fusion reactions within stars.

The relative and arbitrary abundance of 16 o is last because it is a principal cartesian product of stellar development and because IT is a basal isotope, meaning IT can be ready-made by stars that were initially ready-made exclusively of hydrogen.
