GALAH abundance sequences imply about 75% of solar carbon, 60-80% of Sc, Ti, Cu, and Zn, and roughly 30% of europium come from prompt core-collapse sources, while Y, Ba, and La are dominated by delayed enrichment.

Abundance ratios in GALAH DR2 and their implications for nucleosynthesis
GALAH abundance sequences imply about 75% of solar carbon, 60-80% of Sc, Ti, Cu, and Zn, and roughly 30% of europium come from prompt core-collapse sources, while Y, Ba, and La are dominated by delayed enrichment.
