cds-question@unistra.freclipsing-binary-starsccd-photometryinfrared-photometryvisible-astronomybroad-band-photometryWe present multicolor charge-coupled device (CCD) photometry for the eclipsing binary BS Cassiopeiae, observed on four nights between 2007 December and 2008 January. Using the Wilson-Devinney program, the photometric solution was derived from our BVR observations. Photometric results indicated that BS Cas is a W-subtype binary, whose mass ratio and overcontact degree are q=0.2834(+/-0.0010) and f=31.6%(+/-1.1%), respectively. Light curves of BS Cas present a typical O'Connell effect, which may be attributed to dark spot activity of the primary component.2008AJ....136..594Yhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/136/594CatalogResearchIsServedByTAP VizieR generic servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/AJ/136/594https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/AJ/136/594http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/AJ/136/594https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/AJ/136/594https://vizier.iucaa.in/viz-bin/votable?-source=J/AJ/136/594http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/AJ/136/594GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapOpticalInfrareddefaultJ/AJ/136/594/table1CCD photometric observations in BVR-bands for the eclipsing binary BS CasrecnoRecord number assigned by the VizieR team.
