Overview of the underlying assumptions for the production of O, Mg, and Eu for models A, B, C, and D.
| Model | Source of oxygen | Source of magnesium | Source of europium |
|---|---|---|---|
| Model A | CCSNe | CCSNe (+ marginal contribution by SNe Ia) | MRD SNe |
| Model B | CCSNe | CCSNe (reduced) + SNe Ia (increased) | MRD SNe |
| Model C | CCSNe | CCSNe (reduced) + SNe Ia (increased and metal-dependent yields) | MRD SNe |
| Model D | CCSNe | CCSNe (+ marginal contribution by SNe Ia) | MRD SNe (50%) + NSMs (50%) |
Notes. The words ‘increased’ and ‘reduced’ qualify the contribution of a given nucleosynthetic source, and should be understood as relative to the assumptions in model A.
