Impact of varying the mid-plane temperature on the model results. Top: cumulative sulfur abundance fraction of the ten main sulfur carriers for the Nautilus model with T_mid = 10 K. Middle: abundance of sulfuretted species computed assuming T_mid = 10 K versus the abundance computed assuming T_mid = 39 K. We show the names of the species when there is an order of magnitude difference between both models, and plot black dots otherwise. Bottom: abundance of a subset of the most relevant sulfur carriers for the two mid-plane temperatures used.
