Info for the Gaia Catalogue of Nearby Stars

Résumé

The Gaia Catlogue of Nearby Stars is a catalogue of 331,312 objects that contains at least 92% of stars of stellar type M9 within 100pc of the Sun. We estimate that 9% of the stars in this catalogue probably lie outside 100, pc, but when the distance probability function is used, a correct treatment of this contamination is possible. We produced luminosity functions with a high signal-to-noise ratio for the main-sequence stars, giants, and white dwarfs. We examine in detail the Hyades cluster, the white dwarf population, and wide-binary systems and produced candidate lists for all three samples. We detected local manifestations of several streams, superclusters, and halo objects, in which we identified 12 members of the Gaia Enceladus. We present the first direct parallaxes of five objects in multiple systems within 10pc of the Sun.In this poster we provide links to the outreach materials, data access and discussion groups of the GCNS project.
