Extended Data Fig. 8: Evidence for super-solar K/O ratio in WASP-39b.
From: Early Release Science of the exoplanet WASP-39b with JWST NIRISS
We fit for the K/O ratio while keeping the rest of the model parameters (for example, C/O ratio, metallicity and redistribution) the same as our reference model and fitting for the cloud parameters and scaled planetary radius. Here we present the different K/O ratio models (solid lines) we fit against the transmission spectrum at R = 300 (black and white points). We represent the respective fit of each model in the orange shading. (https://github.com/afeinstein20/wasp39b_niriss_paper/blob/main/scripts/edfigure8.py).
