Nucleosynthesis encompasses the network of nuclear reactions that forge the elements within stars and during stellar death. In the cores of main-sequence stars, hydrogen burning via the proton–proton ...

Stellar evolution as a research area investigates the physical processes governing the formation, structural changes, and end states of stars across cosmic time, using stellar structure theory, ...
