cds-question@unistra.freclipsing-binary-starsvisible-astronomymedium-band-photometryIn order to increase the limited number of B-stars with accurately known dimensions, and also the number of well studied eclipsing binaries in open clusters, we have undertaken observations and studies of four southern double-lined eclipsing B-type binaries; DW Car, BF Cen, AC Vel, and NSV 5783. Complete uvby light curves were observed between January 1982 and April 1991 at the Danish 0.5m telescope at ESO La Silla, since 1985 known as the Stroemgren Automatic Telescope (SAT). Standard indices for the systems and the comparison stars, as well as additional minima observations for AC Vel, have been obtained later at SAT. For DW Car and AC Vel, high-resolution spectra for definitive spectroscopic orbits have also been obtained; they are presented as part of the detailed analyses of these systems. A few spectra of NSV 5783 are included in the present paper.2007A&A...461.1065Chttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/461/1065CatalogResearchIsServedByTAP VizieR generic servicerelated-toJ/A+AS/109/425 : AO Vel four-colour photometry (Clausen+, 1995)J/A+AS/112/123 : uvby lightcurves of LZ Cen (Vaz+, 1995)J/A+AS/101/563 : uvby photometry of GG Lup (Clausen+ 1993)J/A+AS/128/251 : uvby photometry of V3903 Sgr (Vaz+ 1998)J/A+AS/115/315 : uvby light curves of the system V539 Arae (Clausen+, 1996)J/A+AS/109/425 : AO Vel four-colour photometry (Clausen+, 1995)J/A+AS/130/245 : Light curves of the PMS system TY CrA (Vaz+ 1998)J/A+A/461/1077 : Radial velocities of DW Car (Southworth+, 2007)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/461/1065https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/461/1065http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/461/1065https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/461/1065https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/461/1065http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/461/1065GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapOpticaldefaultJ/A+A/461/1065/table11DW Carinae uvby light curves (instrumental system).
