cds-question@unistra.freclipsing-binary-starsline-intensitiesradial-velocityThe 22 Vul system is important for studying the winds and chromospheres of cool evolved stars because the G4 I component is rotating rapidly and probably faster than synchronously. We discuss the system's physical properties in the context of a wide range of constraints on them and propose values that may be marginally better than previous ones. We use H{alpha} spectroscopy to assess the variability of the cool star's wind, and archival IUE observations to measure variation of density in the wind and rotation of the chromosphere.2007AJ....133.2669Ehttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/133/2669CatalogResearchIsServedByTAP VizieR generic servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/AJ/133/2669https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/AJ/133/2669http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/AJ/133/2669https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/AJ/133/2669https://vizier.iucaa.in/viz-bin/votable?-source=J/AJ/133/2669http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/AJ/133/2669GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapOpticaldefaultJ/AJ/133/2669/spectroSpectroscopic observations (HRV and H{alpha} equivalent width)recnoRecord number assigned by the VizieR team.
