cds-question@unistra.fryoung-stellar-objectsstellar-associationsUntil the late 1990s the rich Hyades and the sparse UMa clusters were the only coeval, comoving concentrations of stars known within 60 pc of Earth. Both are hundreds of millions of years old. Then beginning in the late 1990s the TW Hydrae Association, the Tucana/Horologium Association, the beta Pictoris Moving Group, and the AB Doradus Moving Group were identified within ~60pc of Earth, and the eta Chamaeleontis cluster was found at 97pc. These young groups (ages 8-50Myr), along with other nearby, young stars, will enable imaging and spectroscopic studies of the origin and early evolution of planetary systems.2004ARA&A..42..685Zhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/other/ARA+A/42.685CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/other/ARA+A/42.685https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/other/ARA+A/42.685http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/other/ARA+A/42.685https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/other/ARA+A/42.685https://vizier.iucaa.in/viz-bin/votable?-source=J/other/ARA+A/42.685http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/other/ARA+A/42.685GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/other/ARA+A/42.685/stars (Stars studied and their membership)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/other/ARA+A/42.685/stars?https://vizier.iucaa.in/viz-bin/conesearch/J/other/ARA+A/42.685/stars?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/other/ARA+A/42.685/stars?GETtext/xml+votable180.050000true153.311667-52.5150.0055555555555555566/129 601 719 765 784 940 1762 2374 2966 10203 12770 13512 13674 15686 16393 16606 16853 16930 17552 20327 20491 20609 21386 22146 22773 23094 23140 23155 23176 23388 24608 24629 24763 25113 26133 30826 31104 32844 33116 33312 33361 33439 33500 33583 33694 33704 33707 33716 33850 34054 34074 34163 34244-34245 34338 34757 34781 34823 34825 34829-34830 34886 34930 34998 35077 35497 36308 36487 36884 36907 36948 37006 37012-37013 37120-37122 37125 37138 37414 37419 38054 38061 38151 38191 38341 38347 38359 38363 38382 38687 38742 38800 38936 38950 39044 39829 41122 41128 41295 41472 41474 41484 41505 41798 42910 43137 43251 43259 43545 43571 43670 43677 43704 44439 45382 45453 45538 45544 45746 45927 45931 45944 45964 46084 46383 46922 47205 47287 47626 47777 48263 48274 48905https://cdsarc.cds.unistra.fr/viz-bin/moc/J/other/ARA+A/42.685?format=asciiOpticaldefaultJ/other/ARA+A/42.685/starsStars studied and their membershipNameStar name (4)meta.id;meta.maincharrecnoRecord number assigned by the VizieR team.
