摘要

描述
Deutsch: Gaia Catalogue of Nearby Stars (GCNS), zum ersten mal veröffentlicht als Unterkatalog in Gaia EDR3. Visualisierung der Objekte mit Parallaxen im Abstand von bis zu 10, 25 und 100 Parsec von der Sonne. Die Größe der Kreise entspricht der Zahl der gefundenen Sterne. Überlappende Bereiche symbolisieren Sterne, die in zwei oder mehr Katalogen zu finden sind. Dunkelbraun:erdbasierte Teleskope, mittelbraun Hipparcos und hellbraun für GCNS.
English: The Gaia Catalogue of Nearby Stars (GCNS) compared to previous compilations. Represented is the number of nearby stars with trigonometric parallaxes within 10 pc, 25 pc and 100 pc. The colours are representative for the catalogue (dark brown for ground-based observatories, medium brown for the ESA Hipparcos catalogue, and light brown for the Gaia GCNS). The area of the circles is proportional to the number of stars. The circles overlap when the stars appear in both or in all three catalogues. Gaia has completed the census by a factor of about 2 within 25 pc and 10 within 100 pc. An examination of the 10 pc sample finds that GCNS provide the first direct parallax of five stars in multiple systems. Image credit: ESA/Gaia/DPAC - CC BY-SA 3.0 IGO
