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 …

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 …

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; …

BANYAN Σ is a new Bayesian algorithm to identify members of young stellar associations
within 150 pc of the Sun. It includes 27 young associations with ages in the range∼ 1–800 …

The SpHere INfrared Exoplanet (SHINE) project is a 500-star survey performed with
SPHERE on the Very Large Telescope for the purpose of directly detecting new substellar …

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 …

In the past decade, observations from space and the ground have found water to be the
most abundant molecular species, after hydrogen, in the atmospheres of hot, gaseous …

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 …

Context. The explosion of observational data on exoplanets gives many constraints on
theoretical models of planet formation and evolution. Observational data probe very large …

Aims. Using the direct-imaging technique, we searched for low-mass companions around
the star AF Lep, which presents a significant proper-motion anomaly (PMa) signal obtained …
