Table 1.
Carbon fraction fc = Σc/Σtot after 1 Myr at 1 au for models limited by vertical transport and models limited by vertical and radial transport.
| Variation | Value | fc at 1 au after 1 Myr |
|
|---|---|---|---|
| only vertical transport | vertical + radial transport | ||
| Fiducial | 1.7 × 10−3 | 0.16 | |
| Higher UV-flux | LUV = 0.1 L⋆ | 5.2 × 10−5 | 0.11 |
| Lower opacity | κ0 = 4 × 103 cm2 g−1 | 6.4 × 10−11 | 0.052 |
| Larger opacity | κ0 = 1 × 105 cm2 g−1 | 0.10 | 0.23 |
| Lower turbulence | α = 10−3 | 0.015 | 0.24 |
| Less small grains | p = 3 | 0.061 | 0.23 |
| Lower fragmentation velocity | vf = 3 m s−1 | 4.0 × 10−8 | 0.12 |
Notes. Initial carbon fraction is fc = 0.25. Only one parameter is varied with respect to the fiducial model.
