cds-question@unistra.freclipsing-binary-starsephemeridesWe present new photometric two-colour observations of the double-lined close binary star VZ CVn. Combining two data sets obtained in 1971-72 and in 2006, the physical parameters of both components were derived. After removing the light variations due to the eclipses and proximity effects, a periodic variation in the more massive component with a dominant period of 1.06876d could be detected in the first photometric data set. In accordance with its position on the Hertzsprung-Russell diagram and both its pulsation period and pulsation constant of 0.62d, the primary component of VZ CVn should be an excellent {gamma} Doradus candidate. The less massive secondary component seems to have smaller radius with respect to its mass. Both components appear to have lower luminosities with respect to their masses; hence, their radiative properties seem to be different. The evolutionary status of the components is also discussed.2007MNRAS.376..573Ihttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/376/573CatalogResearchIsServedByTAP VizieR generic servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/376/573https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/376/573http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/376/573https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/376/573https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/376/573http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/376/573GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapdefaultJ/MNRAS/376/573/table4The new times of minima for VZ CVnrecnoRecord number assigned by the VizieR team.
