We present a new set of solar metallicity atmosphere and evolutionary models for very cool
brown dwarfs and self-luminous giant exoplanets, which we term ATMO 2020. Atmosphere …

High-contrast adaptive optics (AO) imaging is a powerful technique to probe the
architectures of planetary systems from the outside-in and survey the atmospheres of self …

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 …

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 …

We present a large, uniform analysis of young (≈ 10–150 Myr) ultracool dwarfs, based on
new high-precision infrared (IR) parallaxes for 68 objects. We find that low-gravity (vl-g) late …

We present ground-based spectroscopic verification of 6 Y dwarfs (see also Cushing et al.),
89 T dwarfs, 8 L dwarfs, and 1 M dwarf identified by the Wide-field Infrared Survey Explorer …

We present the discovery of seven ultracool brown dwarfs identified with the Wide-field
Infrared Survey Explorer (WISE). Near-infrared spectroscopy reveals deep absorption bands …

Most directly imaged giant exoplanets are fainter than brown dwarfs with similar spectra. To
explain their relative underluminosity, unusually cloudy atmospheres have been proposed …

We report parallax measurements for 70 ultracool dwarfs (UCDs) including 11 late-M, 32 L,
and 27 T dwarfs. In this sample, 14 M and L dwarfs exhibit low surface gravity features, 6 are …

Context. 51 Eridani b is an exoplanet around a young (20 Myr) nearby (29.4 pc) F0-type star,
which was recently discovered by direct imaging. It is one of the closest direct imaging …
