cds-question@unistra.frmultiple-starsinfrared-photometryWe present the results of a near-infrared adaptive optics survey with the aim to detect close companions to Hipparcos members in the three subgroups of the nearby OB association Sco OB2: Upper Scorpius (US), Upper Centaurus Lupus (UCL) and Lower Centaurus Crux (LCC). We have targeted 199 A-type and late B-type stars in the K_S band, and a subset also in the J and H band. We find 151 stellar components other than the target stars. A brightness criterion is used to separate these components into 77 background stars and 74 candidate physical companion stars. Out of these 74 candidate companions, 41 have not been reported before (14 in US; 13 in UCL; 14 in LCC).2005A&A...430..137Khttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/430/137CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/430/137https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/430/137http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/430/137https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/430/137https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/430/137http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/430/137GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/430/137/table1 (Results from the ADONIS adaptive optics survey among 199 Sco OB2 member stars)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/430/137/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/430/137/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/430/137/table1?GETtext/xml+votable180.050000true154.771131-64.6762580.0055555555555555566/29229 29358 37175 37186 37237 37242 37314 37928 37968 37977-37978 38145 38157 38212 38215 38255 38272 41513 41534 41618 41632 41637 41641 41643 41652 41726 41866 41869 41971 42218 42237 42382 42399-42400 42406-42407 42412 42414 42424-42425 42465 42549 42610 42612 42617 42619 42622-42623 42628 42635 42649 42658 42660 42670 42678 42684 42701 42708 42714 42728 42730 42734 42736 42742 42754 42758 42808 42858 42873 42896 42911 42913 42917 42923 42955 42959 42972 42978 42980 42984-42985 42987 42989-42990 42994 43012 43017 43032 43065 43093 43097 43103 43111 43127 43130 43139 43147 43153-43154 43157 43160 43192 43201 43205-43206 43224 43228-43230 43255-43256 43259 43276 43285 43287 43292-43293 43301 43323 43326 43331-43333 43339 43342 43345 43364 43367 43372 43375 43377 43402-43403 43423 43425 43435 43457 43523 43530 43540 43559 44044 44046 44054-44055 44068-44069 44073 44088 44096 44098 44101 44136 44146 44293 44307-44308 44310 44313 44316 44319 44321 44352-44354 44356 44359-44361 44363 44368 44371 44378 44385 44389 44393 44400 44403 44409 44421 44436https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/430/137?format=asciiInfrareddefaultJ/A+A/430/137/table1Results from the ADONIS adaptive optics survey among 199 Sco OB2 member starsrecnoRecord number assigned by the VizieR team.
