cds-question@unistra.freclipsing-binary-starsccd-photometryinfrared-photometryvisible-astronomybroad-band-photometryWe analyze new multicolor light curves and recently published radial velocity curves for close binaries QX And, RW Com, MR Del, and BD +07 3142 to determine the physical parameters of the components. The light curves are analyzed using a binary star model based on Roche geometry to fit the photometric observations. Spectroscopic parameters, such as the mass ratios and spectral types, were taken from recent spectroscopic studies of the systems in question.2011A&A...525A..66Dhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/525/A66CatalogResearchIsServedByTAP VizieR generic servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/525/A66https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/525/A66http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/525/A66https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/525/A66https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/525/A66http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/525/A66GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapOpticalInfrareddefaultJ/A+A/525/A66/bdBRV data for BD +07 3142recnoRecord number assigned by the VizieR team.
