A complete 2.4 to 12 micron JWST emission spectrum of the warm sub-Jovian WASP-80 b yields H2O, CH4, CO, and CO2 detections and a super-solar metallicity of 0.55 dex with C/O of 0.48, matching other hot gas giants.

A Precise Metallicity and Carbon-to-Oxygen Ratio for a Warm Giant Exoplanet from its Panchromatic JWST Emission Spectrum
A complete 2.4 to 12 micron JWST emission spectrum of the warm sub-Jovian WASP-80 b yields H2O, CH4, CO, and CO2 detections and a super-solar metallicity of 0.55 dex with C/O of 0.48, matching other hot gas giants.
