Groundbased and spacecraft telescopic observations, combined with an intensive modeling
effort, have greatly enhanced our understanding of hot giant planets and brown dwarfs over …

The atmosphere of a brown dwarf or extrasolar giant planet controls the spectrum of
radiation emitted by the object and regulates its cooling over time. Although the study of …

Gaia Data Release 3 contains a wealth of new data products for the community.
Astrophysical parameters are a major component of this release, and were produced by the …

We present a new generation of substellar atmosphere and evolution models, appropriate
for application to studies of L-, T-, and Y-type brown dwarfs and self-luminous extrasolar …

Context. The third Gaia data release (Gaia DR3) contains, beyond the astrometry and
photometry, dispersed light for hundreds of millions of sources from the Gaia prism spectra …

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 …

Aerosols are common in the atmospheres of exoplanets across a wide swath of
temperatures, masses and ages,–. These aerosols strongly impact observations of …

Directly detecting thermal emission from young extrasolar planets allows measurement of
their atmospheric compositions and luminosities, which are influenced by their formation …

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 …

Abstract Upcoming James Webb Space Telescope observations will allow us to study
exoplanet and brown dwarf atmospheres in great detail. The physical interpretation of these …
