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.
Direct imaging reveals enhanced metallicity and aligned orbit in 29 Cyg b, supporting protoplanetary disk formation near the deuterium burning limit.
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.
DALI modeling with updated warm chemistry finds C2H2/H2O IR flux ratio in T Tauri disks is sensitive to C/O, total O/H, and small-grain abundance, with JWST data suggesting sub-unity C/O and common enhanced O/H.
A comprehensive public dataset of simulated Ariel exoplanet transmission spectra is released to benchmark detrending algorithms, with an ML baseline highlighting dataset shift risks.
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.
Pandora simulations recover stellar photospheric temperatures to ~30 K with no bias and reduce simple spot contamination from 100-1000 ppm to under 10 ppm, but complex spot geometries leave ~1000 ppm residuals.

NASA's Pandora SmallSat Mission: Simulating the Impact of Stellar Photospheric Heterogeneity and Its Correction
Pandora simulations recover stellar photospheric temperatures to ~30 K with no bias and reduce simple spot contamination from 100-1000 ppm to under 10 ppm, but complex spot geometries leave ~1000 ppm residuals.
