cds-question@unistra.fropen-star-clustersmultiple-starspre-main-sequence-starsWe have carried out a major survey for visual binaries toward the Orion Nebula Cluster, using images obtained with the Advanced Camera for Surveys on the Hubble Space Telescope through an Halpha filter. From 1051 stars more than 60" from theta^1^ Ori C, we have selected 781 that fulfill the criteria for membership in the Orion Nebula Cluster. Among these, we find 78 multiple systems (75 binaries and 3 triples), of which 55 are new discoveries, in the range from 0.1" to 1.5". We perform a statistical study of the 72 binaries and 3 triples that have separations in the limited range 0.15" to 1.5", within which we need no incompleteness correction.2007AJ....134.2272Rhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/134/2272CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toII/171 : Parenago Catalog of Stars in Orion Nebula (Parenago 1954)B/gcvs : General Catalogue of Variable Stars (Samus+ 2007-2010)J/AJ/113/1733 : Orion Nebula Cluster population (Hillenbrand 1997)J/AJ/117/1375 : Orion Trapezium cluster (Simon+, 1999)J/ApJS/160/319 : COUP: observations and source lists (Getman+, 2005)J/MNRAS/361/211 : JHK photometry of brown dwarfs in Orion (Lucas+, 2005)J/A+A/458/461 : Binary stars in the Orion Nebula Cluster (Koehler+, 2006)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/AJ/134/2272https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/AJ/134/2272http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/AJ/134/2272https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/AJ/134/2272https://vizier.iucaa.in/viz-bin/votable?-source=J/AJ/134/2272http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/AJ/134/2272GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/AJ/134/2272/ONCbin (All binaries with angular separation <1.5" outside the 60" exclusion zone around {theta}^1^ Ori C)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AJ/134/2272/ONCbin?https://vizier.iucaa.in/viz-bin/conesearch/J/AJ/134/2272/ONCbin?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AJ/134/2272/ONCbin?GETtext/xml+votable180.050000true83.65875-5.4613890.0055555555555555566/21438 21439 22804 22805https://cdsarc.cds.unistra.fr/viz-bin/moc/J/AJ/134/2272?format=asciiOpticaldefaultJ/AJ/134/2272/ONCbinAll binaries with angular separation <1.5" outside the 60" exclusion zone around {theta}^1^ Ori CrecnoRecord number assigned by the VizieR team.
