Table A.1
Adopted molecular vibrational frequency, desorption energy, atomic mass, and freeze-out temperature.
| Molecule | νia [Hz] | Eia [K] | mi [mH] | Tfo,ib [K] |
|---|---|---|---|---|
| H2O | 4 × 1013 | 5800 | 17.84 | 123 (120) |
| CO2 | 1 × 1013 | 2700 | 43.56 | 58 (50) |
| CO | 7 × 1011 | 1180 | 27.72 | 27 (30) |
| N2 | 8 × 1011 | 1050 | 27.72 | 24 (30) |
| NH3 | 1 × 1013 | 3800 | 16.83 | 83 (80) |
Notes. a Values adopted from table 1 of (Öberg & Wordsworth 2019). b Values computed by assuming s = 0.1 μm, dgr = 10−14, and nH = 1012 cm−3. We obtain this last value directly from our simulations. Adopted values are in parentheses.
