cds-question@unistra.freclipsing-binary-starsmultiple-starsphotometryWe present results of the Canada-France-Hawaii Telescope adaptive optics (AO) search for companions of a homogeneous group of contact binary stars, as a contribution to our attempts to prove the hypothesis that these binaries require a third star to become as close as observed.2007AJ....134.2353Rhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/134/2353CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/AJ/134/2353https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/AJ/134/2353http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/AJ/134/2353https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/AJ/134/2353https://vizier.iucaa.in/viz-bin/votable?-source=J/AJ/134/2353http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/AJ/134/2353GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/AJ/134/2353/table2 (Overview of observed systems and detections of visual companions)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AJ/134/2353/table2?https://vizier.iucaa.in/viz-bin/conesearch/J/AJ/134/2353/table2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AJ/134/2353/table2?GETtext/xml+votable180.050000true347.883693936.89308610.0055555555555555566/454 1118 1314 1441 1679 1933 2499 2952 3201 3559 4425 4427 5110 6844 8357 8716 8871 9514 9890 11278 12338 12885 12953 13181 13618 13699 13859 13908 14528 14576 14723 16186 16719 16820 17310 17508 18234 18902 19075 19312 19448 19698 19998 20270 20993 21919 21969 22080 22081 22680 22696 22786 22929 24232 24378 24391 24983 27116 27603 27770 27852 28129 28143 29810 30491 30565 31148 31781 31843 31944 31950 32307 32713 35741 36650 36759 36805 39933 44514 44981https://cdsarc.cds.unistra.fr/viz-bin/moc/J/AJ/134/2353?format=asciiOpticaldefaultJ/AJ/134/2353/table2Overview of observed systems and detections of visual companionsrecnoRecord number assigned by the VizieR team.
