cds-question@unistra.freclipsing-binary-starsinfrared-photometryvisible-astronomybroad-band-photometryVV Vir is a near-contact but detached mid-G-type eclipsing binary with an asymmetrical light curve due to a weak but regular mass exchange. The binary is apparently approaching contact and has a stream impact spot on the secondary component that is responsible for a quadratically [dP/P=(-7.8+/-0.2)x10^-11^] decreasing period. Our period study included more than 140 minima observed over the past 60 years. We explore other possible near-contact configurations for this binary.2008AJ....136.1667Shttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/136/1667CatalogResearchIsServedByTAP VizieR generic servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/AJ/136/1667https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/AJ/136/1667http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/AJ/136/1667https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/AJ/136/1667https://vizier.iucaa.in/viz-bin/votable?-source=J/AJ/136/1667http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/AJ/136/1667GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapOpticalInfrareddefaultJ/AJ/136/1667/table1Photometry of VV VirrecnoRecord number assigned by the VizieR team.
