Disequilibrium abundances of the dominant molecules in the atmosphere of WASP-117b computed for different vertical eddycoefficients K_zz with the chemical kinetics code of Venot et al. (2012). The gray lines indicate the chemical equilibrium state. The bottom right plot shows the one-dimensional pressure-temperature profile of WASP-117b, calculated with petitCODE (Mollière et al. 2015, 2017). The model setup is based on the warm, slightly enriched scenario for WASP-117b (T_eq =700 K, Z = 5× solar, C/O =0.3).
