| Menv,thresh [M⊕] | 2.6 × 10-6 | 1.35 × 10-4 | 4.9 × 10-3 | 0.12 |
| rP [km] | ≲0.001 | 0.1 | 1–10 | 10–100 |
| Mcross [M⊕] | 1.15 | 1.82 | 2.83 | 4.58 |
| tcross [Myr] | 1.8 | 2.65 | 3.68 | 5.16 |
| trun [Myr] | 2.67 | 2.9 | 3.48 | 4.83 |
| Δtenriched [Myr] | 2.17 | 1.9 | 1.48 | 0.83 |
Notes. Values of envelope mass at the onset of enrichment (Menv,thresh), approximate size of icy particles dissolved in the envelope for the corresponding Mthresh, crossover mass (Mcross), crossover time (tcross), time at which runaway of gas begins (trun), and time during which the envelope is enriched but still not in runaway of gas (Δtenriched). ṀZ = 10-6M⊕/yr for all the cases.
