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 …

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 …

Clouds and hazes are commonplace in the atmospheres of solar system planets and are
likely ubiquitous in the atmospheres of extrasolar planets as well. Clouds affect every aspect …

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 …

Transmission spectra are differential measurements that utilize stellar illumination to probe
transiting exoplanet atmospheres. Any spectral difference between the illuminating light …

We present K-band interferometric observations of the PDS 70 protoplanets along with their
host star using VLTI/GRAVITY. We obtained K-band spectra and 100 μas precision …

We present an update of the open-source photochemical kinetics code VULCAN to include
C–H–N–O–S networks and photochemistry. The additional new features are advection …

Context. Methods used to detect giant exoplanets can be broadly divided into two
categories: indirect and direct. Indirect methods are more sensitive to planets with a small …

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 …
