Adaptive optics (AO) is a technique that corrects for optical aberrations. It was originally
proposed to correct for the blurring effect of atmospheric turbulence on images in ground …

Adaptive optics is a prime example of how progress in observational astronomy can be
driven by technological developments. At many observatories it is now considered to be part …

Direct images of protoplanets embedded in disks around infant stars provide the key to
understanding the formation of gas giant planets such as Jupiter. Using the Subaru …

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 …

We present a statistical analysis of the first 300 stars observed by the Gemini Planet Imager
Exoplanet Survey. This subsample includes six detected planets and three brown dwarfs; …

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 …

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 …

The detection of satellites around extrasolar planets, so called exomoons, remains a largely
unexplored territory. In this work, we study the potential of detecting these elusive objects …

Until recently, infrared observations of exoplanetary atmospheres have typically been
interpreted using models that assumed solar elemental abundances. With the chemical …

Determining the atmospheric structure and chemical composition of an exoplanet remains a
formidable goal. Fortunately, advancements in the study of exoplanets and their …
