Summary

Abstract To reach a deeper understanding of the origin of elements in the periodic table, we construct Galactic chemical evolution (GCE) models for all stable elements from C ( A = 12) to U ( A = 238) from first principles, i.e., using theoretical nucleosynthesis yields and event rates of all chemical enrichment sources. This enables us to predict the origin of elements as a function of time and environment. In the solar neighborhood, we find that stars with initial masses of M > 30 M ⊙ can become failed supernovae if there is a significant contribution from hypernovae (HNe) at M ∼ 20–50 M ⊙ . The contribution to GCE from super-asymptotic giant branch (AGB) stars (with M ∼ 8–10 M ⊙ at solar metallicity) is negligible, unless hybrid white dwarfs from low-mass super-AGB stars explode as s
