Understanding the dominant brown dwarf and giant planet formation processes, and finding
out whether these processes rely on completely different mechanisms or share common …

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 …

The Gemini Planet Imager is a dedicated facility for directly imaging and spectroscopically
characterizing extrasolar planets. It combines a very high-order adaptive optics system, a …

We present a large, uniform analysis of young (≈ 10–150 Myr) ultracool dwarfs, based on
new high-precision infrared (IR) parallaxes for 68 objects. We find that low-gravity (vl-g) late …

Context. In recent decades, direct imaging has confirmed the existence of substellar
companions (exoplanets or brown dwarfs) on wide orbits (> 10 au) around their host stars. In …

Context. Large surveys with new-generation high-contrast imaging instruments are needed
to derive the frequency and properties of exoplanet populations with separations from~ 5 to …

ABSTRACT A new class of high-contrast image analysis algorithms that empirically fit and
subtract systematic noise has lead to recent discoveries of faint exoplanet/substellar …

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 …

We report the discovery of a planetary-mass companion, HD 106906 b, with the new
Magellan Adaptive Optics (MagAO)+ Clio2 system. The companion is detected with Clio2 in …
