cds-question@unistra.frccd-photometryeclipsing-binary-starsinfrared-photometryvisible-astronomybroad-band-photometryWe present the first multicolor CCD photometry for the eclipsing binary V380 Cassiopeia (V380 Cas) observed on 34 nights in 2009 and 2010 at the University of Patras Observatory. The PHOEBE program based on the Wilson-Devinney algorithm was used to analyze the first complete BVRcIc light curves. It was found that V380 Cas was misclassified and it is a well-detached system consisting of two main-sequence stars. A range of solutions found to give satisfactory fits to the observations is also investigated. The first orbital solution based on the photometric mass ratio q=1.08 of almost equal temperatures and masses and orbital inclination of i=86.57{deg} was obtained. In addition, based on all available times of light minima, including 12 new ones, a new orbital period of P=2.714539884 days is given.2012AJ....143...30Chttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/143/30CatalogResearchIsServedByTAP VizieR generic servicerelated-toB/vsx : AAVSO International Variable Star Index VSX (Watson+, 2006-2013)B/gcvs : General Catalogue of Variable Stars (Samus+ 2007-2012)II/150 : Parameters of eclipsing binaries (Brancewicz+, 1980)J/A+A/417/263 : Catalogue of Algol type binary stars (Budding+, 2004)J/AcA/54/207 : Ephemerids of eclipsing binaries (Kreiner, 2004)J/A+A/446/785 : Catalogue of eclipsing variables (Malkov+, 2006)J/MNRAS/373/435 : Angular momentum of Algol binaries (Ibanoglu+, 2006)J/other/JAVSO/38.183 : Time of minima of eclipsing binaries (Samolyk+, 2010)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/AJ/143/30https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/AJ/143/30http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/AJ/143/30https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/AJ/143/30https://vizier.iucaa.in/viz-bin/votable?-source=J/AJ/143/30http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/AJ/143/30GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapOpticalInfrareddefaultJ/AJ/143/30/table1BVRI photometric observations for the eclipsing binary V380 CasrecnoRecord number assigned by the VizieR team.
