cds-question@unistra.frvariable-starsvisible-astronomymedium-band-photometryWe present the results of simultaneous uvby{beta} photometry carried out from 1999 to 2001 of the variable V2109 Cyg together with a spectroscopic analysis based on one high resolution spectrum obtained in 2000. From this study, the star is definitively classified as an evolved {delta} Sct-type variable with solar metal abundances. This conclusion is also supported by the detected multiperiodic pulsational behaviour and the observed variation of the m1 index over the pulsation cycle.2003A&A...407.1059Rhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/407/1059CatalogResearchIsServedByTAP VizieR generic servicerelated-toJ/A+AS/144/469 : Delta Scuti stars (Rodriguez+, 2000)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/407/1059https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/407/1059http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/407/1059https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/407/1059https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/407/1059http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/407/1059GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapOpticaldefaultJ/A+A/407/1059/table2Results of the O-C analysis.recnoRecord number assigned by the VizieR team.
