cds-question@unistra.fropen-star-clustersvariable-starsccd-photometryWe have obtained photometric time-series observations of stars in the open cluster NGC 2506, in order to study pulsating blue stragglers and eclipsing binaries. The data were obtained during a bi-site campaign in early 2005 which involved the Danish 1.54-m telescope at ESO, La Silla, and the Flemish Mercator telescope at La Palma, Spain. Based on these data we increased the number of known variables in NGC 2506 from 5 to 28 through the detection of 3 new pulsating blue stragglers, 15 gamma Doradus stars and 4 new eclipsing binaries, while one variable is of unknown type. We derived orbital periods for two previously known binaries, we performed a tentative mode-identification of the pulsating blue stragglers, and compared B- and I amplitude ratios and phase differences for the gamma Doradus stars to seismic models.2007A&A...465..965Ahttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/465/965CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/465/965https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/465/965http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/465/965https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/465/965https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/465/965http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/465/965GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/465/965/stars (Stellar parameters for the variables in NGC 2506)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/465/965/stars?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/465/965/stars?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/465/965/stars?GETtext/xml+votable180.050000true119.992083-10.7650.0055555555555555566/21586https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/465/965?format=asciiOpticaldefaultJ/A+A/465/965/table1La Silla B time-seriesrecnoRecord number assigned by the VizieR team.
