The basic geometry of the Solar System—the shapes, spacings, and orientations of the
planetary orbits—has long been a subject of fascination as well as inspiration for planet …

Observational surveys for extrasolar planets probe the diverse outcomes of planet formation
and evolution. These surveys measure the frequency of planets with different masses, sizes …

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; …

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 …

The orbital distribution of giant planets is crucial for understanding how terrestrial planets
form and predicting yields of exoplanet surveys. Here, we derive giant planets occurrence …

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 …

High-contrast near-infrared imaging of the nearby star HR 8799 has shown three giant
planets. Such images were possible because of the wide orbits (> 25 astronomical units …

The last decade of direct imaging (DI) searches for sub-stellar companions has uncovered a
widely diverse sample that challenges the current formation models, while highlighting the …

Abstract The Wide Field InfraRed Survey Telescope (WFIRST) is the next NASA
astrophysics flagship mission, to follow the James Webb Space Telescope. The WFIRST …

We report results of a direct imaging survey for giant planets around 80 members of the β
Pic, TW Hya, Tucana-Horologium, AB Dor, and Hercules-Lyra moving groups, observed as …
