Findings
Includes 2347 stars within 30 pc with detailed data
Provides estimates of stellar luminosity, temperature, and planet brightness
Lists known exoplanet companions and stellar characteristics
Abstract
We present the first version of a Nearby Stellar Systems Catalog for Exoplanet Imaging Missions (dubbed by the direct imaging community as "ExoCat") for use in exoplanet direct imaging mission planning. This version, ExoCat-1, includes 2347 stars taken from the Hipparcos Catalogue with measured parallaxes > 33.33 mas (corresponding to a distance of 30 pc). This sample is nearly complete down to V=8, corresponding to stars brighter than ~0.5 solar luminosities (late G-/early K-type dwarf stars at the 30 pc distance limit). For each star we provide astrometry (including Equatorial and Galactic coordinates, parallax, and proper motions), Johnson B and V magnitudes (converted from Hipparcos or Tycho data or taken from the literature), and Ks-band magnitudes from 2MASS (for fainter stars) or K-band magnitudes taken from the literature and converted to 2MASS Ks magnitudes (for bright stars).…
