Carbon and oxygen abundances relative to solar, predicted for Jupiter’s atmosphere assuming different contributing sources.
| Incorporated species | [O/H]/[O/H]⋆ | [C/H]/[C/H]⋆ | C/O |
|---|---|---|---|
| Accretion of N2 enriched gas | |||
| 1: Gaseous N2 and CO | 1.8 | 3.6 | 1.1 |
| 2: 1 + refr. C and H2O ice | 2.7 | 4.0 ( * ) | 0.8 |
| 3: 2 + silicates | 3.3 | 4.0 ( * ) | 0.66 |
| Accretion of N2 rich pebbles | |||
| 1: N2, CO and H2O ice | 3.6 | 3.6 | 0.55 |
| 2: 1 + refractory carbon | 3.6 | 4.5 | 0.7 |
