JWST data on NGTS-10A b shows nightside CH4 depletion caused by day-to-night horizontal transport rather than vertical mixing or non-solar abundances.
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.
The atmosphere of TOI-1130b shows high metallicity, low C/O, and elevated mean molecular weight consistent with ex-situ formation beyond the water ice line.
JWST/NIRCam observations of 2024 YR4 extend the orbital arc by eight months, reduce 2032 lunar encounter uncertainty by >30x, and rule out impact with a 22,900 ± 800 km miss distance.
Accounting for stellar and orbital uncertainties shows that predicted eclipse depths for bare-rock models of rocky exoplanets carry substantial uncertainty comparable to measurements, establishing a fundamental precision limit for atmospheric and compositional inferences.
JWST eclipse data show HD 3167 b has a cooler dayside than a bare rock, indicating an atmosphere on this least-irradiated USP super-Earth with such evidence.
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.
New transit observations of WASP-43 b yield no evidence of orbital decay while revealing major challenges in combining multi-instrument data for atmospheric retrievals.
