Debris disks are tenuous, dust-dominated disks commonly observed around stars over a
wide range of ages. Those around main sequence stars are analogous to the Solar System's …

Since the concept of adaptive optics (AO) was proposed in 1953, AO has become an
indispensable technology for large aperture ground-based optical telescopes aimed at high …

Context. Young circumstellar disks are the birthplaces of planets. Their study is of prime
interest to understand the physical and chemical conditions under which planet formation …

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 …

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 …

The orbital eccentricities of directly imaged exoplanets and brown dwarf companions
provide clues about their formation and dynamical histories. We combine new high-contrast …

Aims. HD 206893 is a nearby debris disk star that hosts a previously identified brown dwarf
companion with an orbital separation of∼ 10 au. Long-term precise radial velocity (RV) …

We report the results of a∼ 4 yr direct imaging survey of 104 stars to resolve and
characterize circumstellar debris disks in scattered light as part of the Gemini Planet Imager …

The orientation between a star's spin axis and a planet's orbital plane provides valuable
information about the system's formation and dynamical history. For non-transiting planets at …
