Exoplanet hunting efforts have revealed the prevalence of exotic worlds with diverse
properties, including Earth-sized bodies, which has fueled our endeavor to search for life …

Over the last two decades, several thousand exoplanets have been identified, and their
study has become a high scientific priority. Direct imaging of nearby exoplanets and the …

A complete accounting of nearby objects—from the highest-mass white dwarf progenitors
down to low-mass brown dwarfs—is now possible, thanks to an almost complete set of …

Directly detecting thermal emission from young extrasolar planets allows measurement of
their atmospheric compositions and luminosities, which are influenced by their formation …

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 …

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 an open-source Python package, Orbits from Radial Velocity, Absolute, and/or
Relative Astrometry (orvara), to fit Keplerian orbits to any combination of radial velocity …

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

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 …
