Table information for 'gcvs_gaia_tess.main'

General

This table is available for ADQL queries and through the TAP endpoint.

Resource Description: This catalog combines photometric and astrometric data from three major sources: the General Catalogue of Variable Stars (GCVS, 2017ARep...61...80S), Gaia DR3, and TESS. It provides detailed information on variable stars, including their coordinates, magnitudes, variability periods, parallaxes, proper motions, spectral classifications, and other physical characteristics. Additionally, the catalog includes computed parameters such as galactocentric distances and model-predicted values for spectral types and variability types for stars with incomplete observational data. The catalog aims to facilitate studies of stellar variability, galactic structure, and stellar evolution.
