Table 1
Best Pareto-optimal model parameters for the different element groups.
| Model | α × YEu [M⊙] | τ [Gyr] | Mmid [M⊙] | D |
|---|---|---|---|---|
| Eu | 2.22 × 10−7 | 0.03 | 22.5 | 6.0 |
| Eu-Zr | 2.94 × 10−7 | 0.01 | 22.5 | 43.0 |
| Sr-Y-Zr | 3.44 × 10−7 | 0.02 | 22.5 | 37.7 |
| Ba-La-Ce | 1.78 × 10−7 | 0.01 | 9.0 | 9.9 |
| Eu-Sr-Y-Zr | 3.01 × 10−7 | 0.02 | 22.5 | 47.4 |
| Eu-Ba-La-Ce | 2.70 × 10−7 | 0.02 | 22.5 | 23.3 |
Notes. The listed parameters are: the Eu injection rate, α×YEu, the delay time, τ, the medium value of the progenitor mass range, Mmid, and the distance to the point 0 in objective space, D.
