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 …

Characterizing the atmospheres of extrasolar planets is the new frontier in exoplanetary
science. The last two decades of exoplanet discoveries have revealed that exoplanets are …

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 …

In this paper, we review the impact of small sample statistics on detection thresholds and
corresponding confidence levels (CLs) in high-contrast imaging at small angles. When …

We present a kinematic analysis of 152 low surface gravity M7-L8 dwarfs by adding 18 new
parallaxes (including 10 for comparative field objects), 38 new radial velocities, and 19 new …

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 …

Abstract The Subaru Coronagraphic Extreme Adaptive Optics (SCExAO) instrument is a
multipurpose high-contrast imaging platform designed for the discovery and detailed …

With four companions at separations from 16 to 71 au, HR 8799 is a unique target for direct
imaging, presenting an opportunity for a comparative study of exoplanets with a shared …

Absorption lines from water, methane, and carbon monoxide are detected in the atmosphere
of exoplanet HR 8799 b. A medium-resolution spectrum presented here shows well …
