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.
Planetary formation tracks on the HR diagram show three branches: ascending during solid accretion with L proportional to T to the 8th for in-situ planetesimals, near-horizontal during gas accretion, and descending during post-accretion cooling.
Direct imaging reveals enhanced metallicity and aligned orbit in 29 Cyg b, supporting protoplanetary disk formation near the deuterium burning limit.
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.
TOI-201 has three planets whose co-transiting configuration will end in 200 years due to Kozai-Lidov oscillations driven by mutual inclinations.
F770W minus F1000W colors below 0.03 mag identify L dwarfs seven times more likely to have silicate clouds, while current models underpredict the 9-micron silicate feature.
Early LSST data recovers known ultracool dwarfs and yields 89 candidates with 17 unique to this work, forecasting over 17,000 detections in Data Preview 2 using synthetic populations.
SPHEREx spectra of 37 field brown dwarfs show atmospheric models struggle with J/H/K peaks and 4um window especially at L/T transition, with data preferring weak-mixing Elf Owl models.
Discovery of an L2 brown dwarf companion (mass 53 M_Jup, age ~280 Myr) to HIP 17453 A via proper-motion confirmed imaging and spectroscopy.
New 4D tables of giant planet atmosphere boundary conditions and spectra with consistent metal EOS, showing on-the-fly interpolation changes late-stage evolution and helium depletion.
TOI-7154b is a 71.7 M_J brown dwarf in an 8.86-day eccentric orbit around a G star, with eccentricity and age suggesting stellar-like fragmentation origins.
Discovery and orbital/stellar characterization of transiting brown dwarf TOI-6884b using TESS photometry corrected by ground-based RV and multi-epoch photometry.
