From: A warm Neptune’s methane reveals core mass and vigorous atmospheric mixing
ATMO non-equilibrium chemistry model with vertical mixing and photochemistry. The best-fit non-equilibrium chemistry model (solid lines) and the abundance profiles in equilibrium (dot-dashed lines) are shown. The retrieved JWST abundances are shown (data points) with the model grid indicating that the planet has hot interior temperatures (Tint = 458 ± 38 K), a super-solar metallicity (Z/Z⊙ = 43 ± 8) with vigorous vertical mixing (Kzz = 1011.6±0.1 cm2 s−1).
