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

Helium is the second-most abundant element in the Universe after hydrogen and is one of
the main constituents of gas-giant planets in our Solar System. Early theoretical models …

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 …

Context. A new class of exoplanets has emerged: the ultra hot Jupiters, the hottest close-in
gas giants. The majority of them have weaker-than-expected spectral features in the 1.1− 1.7 …

The ExoMol database (www. exomol. com) provides extensive line lists of molecular
transitions which are valid over extended temperature ranges. The status of the current …

Infrared radiation emitted from a planet contains information about the chemical composition
and vertical temperature profile of its atmosphere,,. If upper layers are cooler than 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 …

Here we present a publicly available database of opacities for molecules of astrophysical
interest named ExoMolOP that has been compiled for over 80 species, and is based on the …

The temperature profile of a planetary atmosphere is a key diagnostic of radiative and
dynamical processes governing the absorption, redistribution and emission of energy …

The majority of stars are now thought to support exoplanets. Many of those exoplanets
discovered thus far are categorized as rocky objects with an atmosphere. Most of these …
