| Description | r (AU) | τs | Ntot | Nsim | Mplt (M⊕) | Mmin (M⊕) | Mmax (M⊕) | Mtot (M⊕) |
|---|---|---|---|---|---|---|---|---|
| Fiducial | 0.3 | 0.1 | 9943 | 924 | 1.3 × 10−7 | 6.3 × 10−9 | 1.3 × 10−5 | 6.7 × 10−4 |
| Fiducial | 3 | 0.1 | 7470 | 651 | 1.7 × 10−6 | 8.4 × 10−8 | 1.5 × 10−4 | 6.7 × 10−3 |
| Fiducial | 30 | 0.1 | 5618 | 514 | 2.3 × 10−5 | 1.1 × 10−6 | 1.7 × 10−3 | 6.7 × 10−2 |
| Low Stokes number | 0.3 | 0.03 | 13431 | 1224 | 1.7 × 10−7 | 8.5 × 10−9 | 1.9 × 10−5 | 1.2 × 10−3 |
Notes. Ntot is the total number of planetesimals in the belt, Nsim is the number of selected planetesimals for numerical simulations, Mpıt is the characteristic mass, and Mtot is the total mass of the planetesimals. The Stokes number (τs) of pebbles is 0.1 in the fiducial run. For comparison, we set τs = 0.03 for the lower Stokes number run (Sect. 4).
