JWST NIRISS/SOSS data yield a transmission spectrum of the 23 Myr V1298 Tau c showing H2O absorption and an atmospheric metallicity of 14.8^{+56}_{-12} times solar, lower than mature planets of similar mass.
Photochemical kinetic-transport models indicate CS2 abundance in gas giant exoplanets peaks at Teq 500-700 K through CH4-H2S chemistry with S2 photolysis as the driver.
Wind speed measurements in seven ultra-hot Jupiters decrease with temperature, consistent with magnetic drag and implying magnetic field strengths of a few gauss.
Interior structure models show 28 of 34 cold super-puffs are consistent with core accretion while six require non-standard explanations such as impacts or exo-rings.
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.
Updated analysis of TOI-2134 with new TESS sectors and spectra confirms an inner mini-Neptune and outer eccentric sub-Saturn, measures their masses and radii, and reports a 59 degree obliquity for the outer planet via Rossiter-McLaughlin effect.
