Characterizing the atmospheres of extrasolar planets is the new frontier in exoplanetary
science. The last two decades of exoplanet discoveries have revealed that exoplanets are …

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 easy-to-use, publicly available, Python package petitRADTRANS, built for
the spectral characterization of exoplanet atmospheres. The code is fast, accurate, and …

Thousands of exoplanets have now been discovered with a huge range of masses, sizes
and orbits: from rocky Earth-like planets to large gas giants grazing the surface of their host …

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 …

High-resolution spectroscopy (R≥ 25,000) has recently emerged as one of the leading
methods for detecting atomic and molecular species in the atmospheres of exoplanets …

We explore how well spectra from the James Webb Space Telescope (JWST) will likely
constrain bulk atmospheric properties of transiting exoplanets. We start by modeling the …

Context. Clouds are ubiquitous in exoplanet atmospheres and they represent a challenge
for the model interpretation of their spectra. When generating a large number of model …

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 …

This article summarizes a workshop held on March, 2014, on the potential of the James
Webb Space Telescope (JWST) to revolutionize our knowledge of the physical properties of …
