The JWST Early-release Science Program for Direct Observations of Exoplanetary Systems II: a 1 to 20 μm spectrum of the planetary-mass companion VHS 1256 …
We present the highest fidelity spectrum to date of a planetary-mass object. VHS 1256 b is
a< 20 M Jup widely separated (∼ 8'', a= 150 au), young, planetary-mass companion that …

Fundamental parameters and spectral energy distributions of young and field age objects with masses spanning the stellar to planetary regime
We combine optical, near-infrared, and mid-infrared spectra and photometry to construct
expanded spectral energy distributions for 145 field age (> 500 Myr) and 53 young (lower …

Evolutionary models for cool brown dwarfs and extrasolar giant planets. The case of HD 209458
We present evolutionary models for cool brown dwarfs and extra-solar giant planets. The
models reproduce the main trends of observed methane dwarfs in near-IR color-magnitude …

The Hawaii infrared parallax program. I. Ultracool binaries and the L/T transition
We present the first results from our high-precision infrared (IR) astrometry program at the
Canada–France–Hawaii Telescope. We measure parallaxes for 83 ultracool dwarfs …

A continuum from clear to cloudy hot-Jupiter exoplanets without primordial water depletion
Thousands of transiting exoplanets have been discovered, but spectral analysis of their
atmospheres has so far been dominated by a small number of exoplanets and data …

Aerosols in exoplanet atmospheres
Observations of exoplanet atmospheres have shown that aerosols, like in the solar system,
are common across a variety of temperatures and planet types. The formation and …

Neglected clouds in T and Y dwarf atmospheres
As brown dwarfs cool, a variety of species condense in their atmospheres, forming clouds.
Iron and silicate clouds shape the emergent spectra of L dwarfs, but these clouds dissipate …

Population properties of brown dwarf analogs to exoplanets
We present a kinematic analysis of 152 low surface gravity M7-L8 dwarfs by adding 18 new
parallaxes (including 10 for comparative field objects), 38 new radial velocities, and 19 new …
