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; …

BANYAN Σ is a new Bayesian algorithm to identify members of young stellar associations
within 150 pc of the Sun. It includes 27 young associations with ages in the range∼ 1–800 …

Context. The relevance of M dwarfs in the search for potentially habitable Earth-sized
planets has grown significantly in the last years. Aims. In our on-going effort to …

We present a self-consistent, absolute isochronal age scale for young (≲ 200 Myr), nearby
(≲ 100 pc) moving groups in the solar neighbourhood based on homogeneous fitting of …

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 …

Abstract The Apache Point Observatory Galactic Evolution Experiment (APOGEE), one of the
programs in the Sloan Digital Sky Survey III (SDSS-III), has now completed its systematic …

We combine optical, near-infrared, and mid-infrared spectra and photometry to construct
expanded spectral energy distributions for 145 field age (> 500 Myr) and 53 young (lower …

This paper presents a cross-calibrated catalog of Hipparcos and Gaia astrometry to enable
their use in measuring changes in proper motion, ie, accelerations in the plane of the sky …

Context. Expanding the sample of directly imaged companions to nearby, young stars that
are amenable to detailed astrometric and spectroscopic studies is critical for the continued …

Estimates of the mass and age of young stars from their location in the HR diagram are
limited by not only the typical observational uncertainties that apply to field stars, but also by …
