First mid-IR transmission spectrum of TOI-270 d shows molecular features with Bayesian evidence ln B = 2.8-5.3 and identifies candidate trace molecules from an agnostic search of 203 species.
First statistically significant detection of dayside silicate clouds on a Neptunian-mass exoplanet, with CO and CO2 detections and C/O ratio of 0.984 from JWST spectra.
GRAVITY+ observations yield a 12CO/13CO ratio of 91^{+24}_{-17} in β Pictoris b consistent with solar/ISM values and a tentative 1.4% atmospheric variability amplitude.
High-resolution M-band spectroscopy detects super-stellar SiO in TWA 5 B, implying no significant magnesium-silicate clouds and formation consistent with core accretion beyond the CO snowline or gravitational instability with solid enrichment.
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.
High-resolution dayside spectroscopy detects H2O at 2.6σ and CO at 2.3σ in CoRoT-2b, yielding supersolar C/O ratio of 0.91 and subsolar metallicity.
MELTYQ couples magma-atmosphere equilibrium models with spectral retrievals to constrain sub-Neptune magma oxidation states and volatile inventories from transmission spectra.
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.
MOFAT applied to SN2024ggi shows CO triggering inner SiO formation with a receding edge, order-of-magnitude mass drop, clumping signatures, and no dust formation.
Direct imaging reveals enhanced metallicity and aligned orbit in 29 Cyg b, supporting protoplanetary disk formation near the deuterium burning limit.
dopplerkernel parametrizes UHJ projected winds with four parameters (v_jet, sigma_jet, v_wind, phi_sink) and retrieves jet and day-to-night flows from synthetic WASP-76b K-band emission spectra generated by three GCMs.
Panchromatic JWST spectrum of WASP-121 b detects SiO and measures refractory-to-volatile ratios 3x stellar, consistent with mixed solid-gas accretion or migration with continued solid accretion.
Direct pixel-level extraction of NIRISS spectra for WASP-18b followed by cross-correlation yields 4.4σ CO, 3.4σ H2O, and 7.8σ OH detections, with improved abundance constraints from subsequent retrievals.
Tentative CO detection from WASP-33b eclipse data alone with SPIRou validates stacking ingresses/egresses and shows Doppler eclipse mapping can constrain rotation with additional observations.
An intercomparison of planetary evolution codes finds Earth magma oceans solidify in about 4 million years while Venus scenarios show more varied prolonged stages up to 50 million years, with outcomes sensitive to initial volatile budgets and model-specific treatments.
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.
A comprehensive public dataset of simulated Ariel exoplanet transmission spectra is released to benchmark detrending algorithms, with an ML baseline highlighting dataset shift risks.
Atmospheric retrievals on CRIRES+ spectra of 2MASS J0249-0557 c and two eta Pic YMG brown dwarfs give solar-like C/O, metallicity, and carbon isotope ratios, supporting gravitational collapse formation for the companion.
Simulations indicate that order-of-magnitude changes in TiO2 and SiO2 abundances in lava melts produce distinguishable TiO, SiO, and SiO2 features in dry lava planet emission spectra, potentially observable with 12 JWST eclipses for the brightest targets.
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.
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.
Retrievals on six isolated brown dwarfs yield near-solar C/O (0.51-0.63), metallicities, and 12C/13C ratios (91-155) supporting molecular cloud fragmentation origin.
