cds-question@unistra.frinfrared-photometrySince November 2002, we have conducted the largest deep imaging survey of the young, nearby associations of the southern hemisphere. Our goal is detection and characterization of substellar companions at intermediate (10-500AU) physical separations. We have observed a sample of 88 stars, mostly G to M dwarfs, that we essentially identify as younger than 100Myr and closer to Earth than 100pc. The VLT/NACO adaptive optics instrument of the ESO Paranal Observatory was used to explore the faint circumstellar environment between typically 0.1 and 10". We report the discovery of 17 new close (0.1-5.0") multiple systems. HIP 108195AB and C (F1III-M6), HIP 84642AB (a~14AU, K0-M5) and TWA 22AB (a~1.8AU; M6-M6) confirmed comoving systems. TWA 22AB is likely to be a astrometric calibrator that can be used to test evolutionary predictions. Among our complete sample, a total of 65 targets observed with deep coronagraphic imaging. About 240 faint candidates were detected around 36 stars. Follow-up observations VLT or HST for 83% of these stars enabled us to identify a fraction of contaminants. The latest results about the substellar companions to GSC 08047-00232, AB Pic and 2M1207, confirmed during this survey and published earlier, are reviewed. Finally, the statistical analysis of our complete set of coronagraphic limits enables us to place constraints on the physical and properties of giant planets between typically 20 and 150AU.2010A&A...509A..52Chttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/509/A52CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/509/A52https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/509/A52http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/509/A52https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/509/A52https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/509/A52http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/509/A52GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/509/A52/table23 (Sample of southern young, nearby stars observed during our VLT/NACO deep imaging survey (tables 2 and 3 of the paper))https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/509/A52/table23?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/509/A52/table23?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/509/A52/table23?GETtext/xml+votable180.050000true154.362083-53.9077780.0055555555555555566/16393 16853 16930 21788 24580 24629 24716 25512 27395 28753 29569 30288 32836 32909 32937 33116 33312 33493 33500 33508 33548 33706 33716 34054 34074 34245 34733 34757 34825 34886 34909 34930 34998 35075 36909 36948 37012 37560 37856 38054 38151 38191 38341 38347 38382 38936 38950 39044 39584 40084 41158 41295 41647 41670 41798 41841 42021 42216 42242 42601 43251 43339 43533 43555 43676-43677 43704 44439 44751 45247 45269 45492 45538 45621 45746 45944 45964 46236 47205 47287 47626 47863 48163 48801https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/509/A52?format=asciiInfrareddefaultJ/A+A/509/A52/table23Sample of southern young, nearby stars observed during our VLT/NACO deep imaging survey (tables 2 and 3 of the paper)recnoRecord number assigned by the VizieR team.
