Disk and planetesimal formation parameters used in our study.
| Symbol | Value | Meaning |
|---|---|---|
| Mstar | 1.0 M⊙ | Mass of the central star |
| Mdisk | 0.1 M⊙ | Total mass of the gas disk |
| ain | 0.03au | Inner disk radius |
| aout | 20au | Exponential cutoff radius |
| γ | 1.0 | initial Σg profile (Σg ∝ r−γ) |
| dg | 1.34 × 10−2 | Dust-to-gas ratio |
| α | 3.0 × 10−4 | Turbulence parameter |
| Lx | 3.0 × 1029 ergs s−1 | X-ray luminosity |
| υfrag | 200 cms−1 | Fragmentation velocity |
| ϵ | 0.05 | ΣP formation efficiency |
| d | 5h | ΣP trap distance |
| h | cs/Ω | Gas pressure scale height |
| τf | 1600torbit | ΣP trap lifetime |
| ρs | 1.0 g cm−3 | ΣP solid density |
Notes. The set of parameters stems from the most appealing solar nebula, as described in Lenz et al. (2020). The planetesimal trap distance d is set to 5 gas pressure scale heights (h = cs/Ω with cs as the local speed of sound and Ω as the Kepler frequency).
