cds-question@unistra.frmultiple-starsexoplanetsstellar-spectral-typesinfrared-photometryproper-motionsradial-velocitystellar-distancesurveysWe report results from the Wide-orbit Exoplanet search with InfraRed Direct imaging, or WEIRD, a survey designed to search for Jupiter-like companions on very wide orbits (1000-5000 au) around young stars (<120 Myr) that are known members of moving groups in the solar neighborhood (<70 pc). Companions that share the same age, distance, and metallicity as their host while being on large enough orbits to be studied as "isolated" objects make prime targets for spectroscopic observations, and they are valuable benchmark objects for exoplanet atmosphere models. The search strategy is based on deep imaging in multiple bands across the near-infrared domain. For all 177 objects of our sample, z'_ab_, J, [3.6], and [4.5] images were obtained with CFHT/MegaCam, GEMINI/GMOS, CFHT/WIRCam, GEMINI/Flamingos-2, and Spitzer/IRAC. Using this set of four images per target, we searched for sources with red z'_ab_ and [3.6]-[4.5] colors, typically reaching good completeness down to 2 M_Jup_ companions, while going down to 1 M_Jup_ for some targets, at separations of 1000-5000 au. The search yielded four candidate companions with the expected colors, but they were all rejected through follow-up proper motion observations. Our results constrain the occurrence of 1-13 M_Jup_ planetary-mass companions on orbits with a semimajor axis between 1000 and 5000 au at less than 0.03, with a 95% confidence level.2018AJ....156..137Bhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/156/137CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/PASP/122/162 : Direct imaging of exoplanets (Beichman+, 2010)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/AJ/156/137https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/AJ/156/137http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/AJ/156/137https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/AJ/156/137https://vizier.iucaa.in/viz-bin/votable?-source=J/AJ/156/137http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/AJ/156/137GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/AJ/156/137/sample (Properties of the bona fide members (tables 2 and 3))https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AJ/156/137/sample?https://vizier.iucaa.in/viz-bin/conesearch/J/AJ/156/137/sample?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AJ/156/137/sample?GETtext/xml+votable180.050000true1.4689167-41.75305560.005555555555555556Cone search capability for table J/AJ/156/137/table8 (Properties of the candidates without MIPS data or detection)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AJ/156/137/table8?https://vizier.iucaa.in/viz-bin/conesearch/J/AJ/156/137/table8?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AJ/156/137/table8?GETtext/xml+votable180.050000true41.502955.583561110.005555555555555556Cone search capability for table J/AJ/156/137/table9 (Properties of the candidates identified through color cuts)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AJ/156/137/table9?https://vizier.iucaa.in/viz-bin/conesearch/J/AJ/156/137/table9?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AJ/156/137/table9?GETtext/xml+votable180.050000true48.085635-44.4269380.0055555555555555566/46 129 483 601 719 722 765 784 826 940 1412 1762 1787 2374 2516 2660 2966 3163 9507 10203 10381 10771 13355 13512 13670 13674 13688 14640 15686 15692 16426 16455 16543 16606 16853 16930 17274 17552 17606 17607 17887 18797 19163 19777 20125 20491 20505 20507 20591 20602 20657 20658 21050 21145 21180 21386 22146 22683 22773 22964 23094 23140 23155 23176 23388 23870 23895 24580 24608 24629 24716 24740 24763 25113 26133 27884 30826 31104 32844 32891 33116 33193 33312 33334 33361 33500 33694 33704 33707 33850 33937 34054 34074 34164 34244 34245 34338 34406 34450 34464 34509 34757 34781 34823 34825 34829 34830 34886 34930 34998 35018 35077 35149 35497 35640 35861 36036 36487 36713 36907 36969 37006 37414 37419 38054 38061 38341 38359 38363 38382 38489 38742 38936 38950 39044 39584 39735 39829 41158 41295 41361 41681 41798 42021 42910 43677 43704 44439 45247 45382 45538 45544 45746 45927 45944 45964 46084 46383 46469 46615 46922 47125 47205 47287 47626 47703 47777 48263 48274 48361 48648 48651 489053.830199579824256e-20 6.513807192489934e-20https://cdsarc.cds.unistra.fr/viz-bin/moc/J/AJ/156/137?format=asciiInfrareddefaultJ/AJ/156/137/sampleProperties of the bona fide members (tables 2 and 3)SimbadNameSimbad column added by the CDSmeta.idcharrecnoRecord number assigned by the VizieR team.
