Spatial distribution (moment 0) maps (white contours) of the o-H 2 CS(7 1,6 -6 1,5 ) line (see Fig. 1), overlaid on the o-H 2 CO(3 1,2 − 2 1,1 ) reported by Podio et al. (2020a), in black contours and red scale. Symbols are as in Figure 1.

Aims: To trace the radial and vertical spatial distribution of H2CS, a key species of the S-bearing chemistry, in protoplanetary disks. To analyse the observed distributions in light of the H2CS binding energy, in order to discuss the role of thermal desorption in enriching the gas disk component. Methods: In the context of the ALMA chemical survey...

... comparison between the moment 0 distributions of H 2 CS with those of H 2 CO ( Podio et al. 2020a) is also instructive (see Fig. 6), showing a slightly different radial distribution of H 2 CO and H 2 CS. The H 2 CO (and CS) emissions extend radially out to ∼ 480 au and peak at ∼ 120 au, while the H 2 CS emission is radially confined in the inner 115 au with a peak at ∼ 70 au. The radial distribution of H 2 CS suggests that the o-H 2 CS(7 1,6 -6 1,5 ) line probes an ...
