Exoplanetary science is on the verge of an unprecedented revolution. The thousands of
exoplanets discovered over the past decade have most recently been supplemented by …

Sensing of gas molecules is critical to environmental monitoring, control of chemical
processes, agricultural, and medical applications. In particular, the detection of industrial …

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 …

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 …

Direct imaging of gas giant exoplanets provides information on their atmospheres and the
architectures of planetary systems. However, few planets have been detected in blind …

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 present here the analysis of 30 gaseous extrasolar planets, with temperatures between
600 and 2400 K and radii between 0.35 and 1.9 R Jup. The quality of the HST/WFC3 …

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. High-resolution spectrographs fed by adaptive optics (AO) provide a unique
opportunity to characterize directly imaged exoplanets. Observations with such instruments …

Exoplanet discoveries of recent years have provided a great deal of new data for studying
the bulk compositions of giant planets. Here we identify 47 transiting giant planets (20 M⊕< …
