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 …

High-contrast observations in optical and infrared astronomy are defined as any observation
requiring a technique to reveal a celestial object of interest that is in such close angular …

We report the discovery and characterisation of a super-Earth and a sub-Neptune transiting
the bright (K= 8.8), quiet, and nearby (37 pc) M3V dwarf TOI-1266. We validate the planetary …

We examine the spectra and infrared colors of the cool, methane-dominated atmospheres at
T_ {\mathrm {eff}\,}\leq 1400 K expected for young gas giant planets. We couple these …

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 present results from a high-contrast adaptive optics imaging search for giant planets and
brown dwarfs (≳ 1 M Jup) around 122 newly identified nearby (≲ 40 pc) young M dwarfs …

Context. High contrast and high angular resolution imaging is the optimal search technique
for substellar companions to nearby stars at physical separations larger than typically 10 AU …

We describe a new instrument that forms the core of a long-term high contrast imaging
program at the 200 inch (5 m) Hale Telescope at Palomar Observatory. The primary …

Doppler surveys have shown that more massive stars have significantly higher frequencies
of giant planets inside∼ 3 AU than lower mass stars, consistent with giant planet formation …
