Table D.2
Maximum total column density (Nmax), radius at which Nmax is reached, maximum abundance of species (ϵmax), and the total column density at a radius of 0.1 au (N) in models with canonical and enhanced C/O elemental ratios.
| Species | Canonical Model (C/O = 0.45) | Enhanced Model (C/O = 2) | ||||||
|---|---|---|---|---|---|---|---|---|
