Summary of the models presented in this study predicting the number of stars hosting terrestrial planets with life (N★,mHC).
| Models | PE([Fe/H]) see Fig. 1 | SN effects | Stellar migration | σRM (kpc) |
|---|---|---|---|---|
| Model 1 | GG BAD | Case 2 | No | / |
| Model 2 | GG BAD | Case 1 | No | / |
| Model 3 | GG BAD | Case 2 | Yes | 3.5 |
| Model 4 | GG BAD | Case 2 | Yes | 6.0 |
| Model 5 | GG GOOD | Case 2 | Yes | 3.5 |
| Model 6 | GG GOOD | Case 2 | Yes | 6.0 |
| Model 7 | GG GOOD | Case 2 | No | / |
Notes. Model names are given in the first column. The adopted probability, PE, of finding terrestrial planets as the function of the metallicity in the presence of gas giants is indicated in the second column. The SN damage model (case 1 or case 2) is reported in the third column. The presence of the stellar migration and the value of the migration strength, σRM, are indicated in the fourth and last columns, respectively.
