Table 5
Atmospheric carbon-to-oxygen ratios for the synthetic planets.
| Model | PDS 70b | PDS 70c |
|---|---|---|
| C/O = 1.01; Visc | 0.84 | |
| C/O = 1.01; Wind | 0.99 (0.990–0.997) | 1.00 (0.999–1.001) |
| C/O = 0.4; Visc | 0.43 | |
| C/O = 0.4; Wind | 0.40 (0.402–0.403) | 0.40 (0.402–0.402) |
Notes. Each row denotes a different combination of disk model and chemical model. As shown in Fig. 9, our viscous disk model fails to produce a satisfactory planet c. Where possible, the ranges of C/O from individual synthetic planets are shown to the third decimal place.
