Do you want to find 'supernova nucleosynthesis process'? You will find your answers right here.
Supernova nucleosynthesis is the nucleosynthesis of chemic elements in supernova explosions. In sufficiently massive stars, the nucleosynthesis by coalition of lighter elements into heavier ones occurs during consecutive hydrostatic burning processes called helium afire, carbon burning, O burning, and atomic number 14 burning, in which the byproducts of one nuclear fire become, after compressional heating, the fire for the ulterior burning stage.

Where does nucleosynthesis occur on the periodic table?
A rarer process, supernova nucleosynthesis, occurs within exploding stars and is responsible for creating elements numbered from 6 (carbon) to 28 (nickel) on the periodic table, according to first reports detailed by Sir Fred Hoyle in 1954. [1] Sir Fred Hoyle
What happens during the core collapse of a supernova?
That uncertainty remains in the full description of core-collapse supernovae. Nuclear fusion reactions that produce elements heavier than iron absorb nuclear energy and are said to be endothermic reactions. When such reactions dominate, the internal temperature that supports the star's outer layers drops.
When did nucleosynthesis occur in the Big Bang?
Nucleosynthesis is a process by which new atomic nuclei are constructed from existing protons and neutrons. The first existence of this process in the universe arose in the Big Bang, during which light elements like hydrogen, helium, and lithium were formed, eventually coalescing into the earliest stars.
What kind of nucleosynthesis happens in a supernova?
Supernova nucleosynthesis. Jump to navigation Jump to search. Supernova nucleosynthesis is a theory of the nucleosynthesis of the natural abundances of the chemical elements in supernova explosions, advanced as the nucleosynthesis of elements from carbon to nickel in massive stars by Fred Hoyle in 1954.
