cds-question@unistra.frstellar-associationsmultiple-starsinfrared-photometryWe present the results of a search for wide binary systems among 783 members of three nearby young associations: Taurus-Auriga, Chamaeleon I, and two subgroups of Upper Scorpius. Near-infrared (JHK) imagery from 2MASS was analyzed to search for wide (1"-30"; ~150-4500AU) companions to known association members, using color-magnitude cuts to reject likely background stars. We identify a total of 131 candidate binary companions with colors consistent with physical association, of which 39 have not been identified previously in the literature.2007ApJ...662..413Khttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/662/413CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toII/246 : 2MASS All-Sky Catalog of Point Sources (Cutri+ 2003)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJ/662/413https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJ/662/413http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJ/662/413https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJ/662/413https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJ/662/413http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJ/662/413GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/ApJ/662/413/table2 (Confirmed Members of Nearby Young Associations)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJ/662/413/table2?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJ/662/413/table2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJ/662/413/table2?GETtext/xml+votable180.050000true167.6450417-77.36813890.0055555555555555565/270 292 5887 9239 10687 10747 11029 11077 11079 11088 11090 11091 11094 11096 11097 6/336 337 342 473 478 1029 1031 1037 1039 1040 1047 1048 1050 1051 1052 1053 1054 1061 1069 1073 1074 1075 1078 1079 1084 1111 1114 1115 1123 1124 1126 1132 1136 1154 1156 1159 1164 1180 1199 23533 23543 24198 24201 24203 24232 24294 24295 24300 30729 36955 37128 42719 42727 42735 42736 42739 42741 42742 42746 42747 42890 42912 42914 42920 42924 42930 42932 42934 42939 42941 42943 42976 42979 42980 42981 42982 42985 42986 42987 42994 42995 42999 43000 43001 43002 43004 43005 44101 44111 44113 44114 44121 44125 44126 44146 44151 44288 44289 44291 44295 44297 44301 44303 44304 44305 44307 44315 44333 44337 44356 44357 44358 44368 44369 44372 44397 44400 44401 44402 44404 44408 44483https://cdsarc.cds.unistra.fr/viz-bin/moc/J/ApJ/662/413?format=asciiInfrareddefaultJ/ApJ/662/413/table3Close Pairs of Confirmed Association MembersSimbadNameSimbad column added by the CDSmeta.idcharrecnoRecord number assigned by the VizieR team.
