Geneva-Copenhagen Survey of Solar Neighbourhood

Part of the Astronomy Datasets collection on Hugging Face.

The Geneva-Copenhagen Survey (GCS) is a comprehensive catalog of 16,682 F and G dwarf stars in the solar neighbourhood, providing ages, metallicities, and full 3D space velocities. It is one of the most widely used datasets for studying the chemical and dynamical evolution of the Milky Way disk.

Dataset description

The GCS combines Stromgren photometry, Hipparcos astrometry, and radial velocities to derive fundamental stellar parameters. The third revision (Casagrande et al. 2011) provides improved effective temperatures based on the infrared flux method and re-derived ages, metallicities, and kinematics. This catalog is essential for studies of the age-metallicity relation, Galactic chemical evolution, and stellar population kinematics in the solar neighbourhood.
