Overview
Core model: Stellar Nucleosynthesis
Stellar nucleosynthesis is the set of nuclear processes that build new atomic nuclei inside stars and during stellar explosions. Different temperature, density, neutron exposure, and evolutionary stages favor different reaction networks, so the periodic table records contributions from multiple astrophysical environments.
