Table 2
Initial abundances of volatile species with respect to total H-nuclei in the inheritance and reset scenarios, together with their binding energies.

| He | 9.5 × 10-2 | 9.5 × 10-2 | 100 | CO2 | 3.0 × 10-5 | — | 2990 |
| C | — | 9.1 × 10-5 | 800 | CH4 | 9.0 × 10-6 | — | 1090 |
| O | — | 2.6 × 10-4 | 800 | CH3OH | 2.2 × 10-5 | — | 4930 |
| N | — | 7.1 × 10-5 | 800 | N2 | 2.4 × 10-5 | — | 790 |
| NH3 | 2.4 × 10-5 | — | 3130 |
Notes. Binding energies from Eistrup et al. (2016). Note that the total elemental abundances listed here match those of the residual gas in Table 1, except for carbon, which excludes the fraction locked in Cref beyond 5 au.
