cds-question@unistra.frstellar-associationspre-main-sequence-starsinfrared-sourcesWe report on a high-spatial-resolution survey for binary stars in the periphery of the Orion Nebula Cluster, at 5-15arcmin (0.65-2pc) from the cluster center. We observed 228 stars with adaptive optics systems, in order to find companions at separations of 0.13"-1.12" (60-500AU), and detected 13 new binaries. Combined with the results of Petr (1998, Ph.D. Thesis, University of Heidelberg), we have a sample of 275 objects, about half of which have masses from the literature and high probabilities to be cluster members.2006A&A...458..461Khttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/458/461CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/AJ/113/1733 : Orion Nebula Cluster population (Hillenbrand 1997)J/ApJ/582/382 : Chandra X-ray sources in ONC (Flaccomio+, 2003)J/AJ/129/1534 : Mid-IR photometry in the Orion Nebula (Robberto+, 2005)J/ApJS/160/353 : Membership of the Orion nebula population (Getman+, 2005)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/458/461https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/458/461http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/458/461https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/458/461https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/458/461http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/458/461GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/458/461/table1 (Fields observed for this work)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/458/461/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/458/461/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/458/461/table1?GETtext/xml+votable180.050000true83.62184583-5.400102780.005555555555555556Cone search capability for table J/A+A/458/461/table2 (New ONC Binaries found in this work)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/458/461/table2?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/458/461/table2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/458/461/table2?GETtext/xml+votable180.050000true83.76494167-5.490850.005555555555555556Cone search capability for table J/A+A/458/461/table6 (Complete target list)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/458/461/table6?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/458/461/table6?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/458/461/table6?GETtext/xml+votable180.050000true83.621667-5.3991670.0055555555555555566/21438-21439 22804-22805https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/458/461?format=asciiInfrareddefaultJ/A+A/458/461/table1Fields observed for this workRAJ2000Right ascension (J2000)pos.eq.ra;meta.mainrecnoRecord number assigned by the VizieR team.
