VizieR Online Data Catalog: Fifth Catalogue of Nearby Stars (CNS5) (Golovin+, 2023)
Abstract
The Fifth Catalogue of Nearby Stars (CNS5) aims to provide the most volume-complete sample of stars in the solar neighbourhood. The CNS5 is compiled based on trigonometric parallaxes from Gaia EDR3 and Hipparcos, and supplemented with astrometric data from Spitzer and ground-based surveys carried out in the infrared. The CNS5 catalogue is statistically complete down to 19.7mag in G-band and 11.8mag in W1-band absolute magnitudes, corresponding to a spectral type of L8. Continuous updates of observational data for nearby stars from all sources were collected and evaluated. For all known stars in the 25 pc sphere around the Sun, the best values of positions in space, velocities, and magnitudes in different filters are presented.
