Extended Data Fig. 8: The main sulfur species abundances with reduced and enhanced UV irradiation.
From: Photochemically produced SO2 in the atmosphere of WASP-39b
VMR profiles of the main sulfur species in the VULCAN morning-terminator model with 0.1× (a) and 10× (b) UV. Our nominal model is shown by solid lines for comparison, whereas the model with varying FUV (1–230 nm) is shown by the dashed lines and that with varying NUV (230–295 nm) is shown by dashed-dotted lines.
