Extended Data Fig. 7: Photochemical model results for d203-506 adopting G0 = 4 × 104 and different gas densities (nH) and dust grain properties.
From: Formation of the methyl cation by photochemistry in a protoplanetary disk
Upper panels: Density and gas temperature structure as a function of visual extinction (AV) from the wind surface. The gray curve shows the density of vibrationally excited H2*(v > 0). Lower panels: Abundance profiles with respect to H nuclei. The pink dotted curves show the molecular fraction \({f}_{{H}_{2}}\) profile. Dashed curves in model a) refer to a model with the same gas density but G0 lower by a factor 104.
