Table 2
Disk initial parameters adopted for two-pop-py population synthesis.
| Parameter | Description | Range | |
|---|---|---|---|
| α | Viscosity parameter | 10−4−10−2 | log uniform |
| Mdisk (Mstar) | Initial disk mass | 10−3−0.5 | log uniform |
| Mstar (M⊙) | Stellar mass | 0.2–2.0 | IMF |
| rc (au) | Characteristic radius | 10–230 | log uniform |
| vfrag (cm/s) | Fragmentation velocity | 200–2000 | Uniform |
| mp (M⊕) | Planet mass | 1–1050 | Uniform |
| rp (rc) | Planet position | 0.05–1.5 | Uniform |
| tp (Myr) | Planet formation time | 0.1–0.4 | Uniform |
Notes. Disk initial parameters and corresponding PDF from which their value is drawn for each single simulation. The drawing of the mp value was performed after the Mdisk to impose the further physically reasonable restriction of mp < Mdisk. In the case of multiple substructures, we applied the following constraint: ∑i mp,i < Mdisk for all planets, i.
