cds-question@unistra.fropen-star-clustersvariable-starsccd-photometryWe report on the discovery of 141 further variable stars found in the field of the open cluster NGC 6819. The stars were identified from time-series photometric data obtained on the Isaac Newton Telescope, La Palma, during two observing runs covering the 19 nights between 1999 June 22-30 and 1999 July 22-31. The variables found include 53 eclipsing binaries, of which eight stars appear to be RS CVns, in addition to 70 stars showing spot activity, 13 showing long-period variability and five variables of other types.2005MNRAS.358..795Shttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/358/795CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/358/795https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/358/795http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/358/795https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/358/795https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/358/795http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/358/795GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/358/795/var (Details of all variables detected)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/358/795/var?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/358/795/var?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/358/795/var?GETtext/xml+votable180.050000true295.562708340.07836110.0055555555555555565/3688 6/https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/358/795?format=asciiOpticaldefaultJ/MNRAS/358/795/varDetails of all variables detectedf_SHLPFlag on star (2)meta.codecharSHLPStar number, Cl* NGC 6819 SHLP NNNNN in Simbadmeta.id;meta.mainintrecnoRecord number assigned by the VizieR team.
