cds-question@unistra.frvariable-starsThis file contains Galactic stars known or suspected to be variable. It lists all stars that have an entry in the AAVSO International Variable Star Index (VSX; http://www.aavso.org/vsx). The database consisted initially of the General Catalogue of Variable Stars (GCVS) and the New Catalogue of Suspected Variables (NSV) and was then supplemented with a large number of variable star catalogues, as well as individual variable star discoveries or variables found in the literature. Effort has also been invested to update the entries with the latest information regarding position, type and period and to remove duplicates. The VSX database is being continually updated and maintained. For historical reasons some objects outside of the Galaxy have been included.2006SASS...25...47Whttps://cdsarc.cds.unistra.fr/viz-bin/cat/B/vsxCatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toB/gcvs : General Catalogue of Variable Stars (Samus+ 2007-2009)http://www.aavso.org/ : the American Associatation of Variable Star Observershttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=B/vsxhttps://vizier.iucaa.in/viz-bin/VizieR-2?-source=B/vsxhttp://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=B/vsxhttps://vizier.cds.unistra.fr/viz-bin/votable?-source=B/vsxhttps://vizier.iucaa.in/viz-bin/votable?-source=B/vsxhttp://vizieridia.saao.ac.za/viz-bin/votable?-source=B/vsxGETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table B/vsx/vsx (Variable Star indeX, Version 2026-05-17)https://vizier.cds.unistra.fr/viz-bin/conesearch/B/vsx/vsx?https://vizier.iucaa.in/viz-bin/conesearch/B/vsx/vsx?http://vizieridia.saao.ac.za/viz-bin/conesearch/B/vsx/vsx?GETtext/xml+votable180.050000true6e-05-75.869060.0055555555555555560/0-11 6/https://cdsarc.cds.unistra.fr/viz-bin/moc/B/vsx?format=asciidefaultB/vsx/vsxVariable Star indeX, Version 2026-05-17n_OIDmeta.ref.urlcharType?
