JWST MIRI/LRS data combined with archival observations detect magnesium silicate clouds (likely Mg2SiO4) in HD 209458b at 1-10 mbar with ~0.1 micron particles using a new rule-based data reduction approach.
Joint speckle-atmosphere retrievals on JWST spectra of HD 19467 B and a field T dwarf detect H2O, CH4, CO, CO2 and NH3, yield carbon isotopic ratios of 154 and 85 respectively, and show near-solar metallicity with subsolar C/O.
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.
Exo-REM k26 grids with f_sed and a two-column patchy-cloud framework fit VHS 1256 b with a 60-40 thick-thin split and reproduce the 10 μm silicate feature.
