Input parameters for the chemical evolution models represented in Figure 6.
| Model Name | Chemical evolution scenario | Yields for AGB | Yields for MS |
|---|---|---|---|
| Model 2 | Three-infall model | FRUITY original | (1) − vrot = 150 km s 1 |
| Model 3 | Three-infall model | FRUITY reduced for Z ≥ 1.4 × 10−2 (0.1x) | (1) − vrot = 150 km s−1 |
| Model 4 | Three-infall model | FRUITY original + 1.1 M⊙ star (10x production) | (1) − vrot = 150 km s−1 |
| Model 5 | Three-infall model | FRUITY original + 1.1 M⊙ star (20x production) | (1) − vrot = 150 km s−1 |
Notes. The models differ by the yields used for AGB stars. In Model 3, AGB yields are reduced by a factor of 10 for metallicities Z ≥ 1.4 × 10−2. In Model 4, a 1.1 M⊙ star with the same prescriptions as the 1.3 M⊙ star is added to the AGB yields, with its production increased by a factor of 10. In Model 5, the 1.1 M⊙ star’s production is increased by a factor of 20. Model 2 uses the original FRUITY yields. See text for more details. (1) Limongi & Chieffi (2018).
