JWST spectroscopy of SIMP 0136 shows variability from three atmospheric regions linked to layers with forsterite clouds and water, using PCA, model combinations, and two new mapping methods.
WASP-96b shows super-solar metallicity of 2-6x stellar, roughly stellar C/O, tentative SO2 consistent with photochemistry, and an optical slope from scattering aerosols, supporting core-accretion formation beyond the water snowline.
The paper reviews physical processes, modeling techniques, retrieval methods, and observational strategies for characterizing exoplanet atmospheres, emphasizing Swiss research progress.
