cds-question@unistra.frstellar-associationsdwarf-starslate-type-starsinfrared-photometryproper-motionsWe associate 132 low-mass ultracool dwarfs in the southern hemisphere as candidate members of five moving groups (MGs) using photometric and astrometric selection techniques. Of these objects, we present high-resolution spectroscopy for seven candidates and combine these with previous measurements from the literature to determine spectral types and radial velocities. We thus constrain distance and space motion spectroscopically, allowing the kinematic membership of the MGs to be assessed. Possible membership of MGs has allowed ages and metallicities to be constrained for these objects and evolutionary models have been used to estimate their mass. We estimate that up to ~75 of our candidate MG members should be genuine, and discuss future work that will confirm and exploit this major new sample.2010MNRAS.402..575Chttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/402/575CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/MNRAS/328/45 : Late-type stars members of young groups (Montes+, 2001)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/402/575https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/402/575http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/402/575https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/402/575https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/402/575http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/402/575GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/402/575/table2 (Properties of the 132 MG candidates)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/402/575/table2?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/402/575/table2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/402/575/table2?GETtext/xml+votable180.050000true1.0790417-57.35647220.0055555555555555566/16426 16528 16539 16601 16632 16696 16725 16754 16770 16981 16990 17594 17985 20531 23183 24887 25015 25186 25894 30925 32860 32960 33003 33199 33223 33277 33444 33492 33609 33819 33949 34075 34401 34535 34587 34622 34640 34954 34961 34981 35020 35082 35168 35231 35235 35251 35297 35312 35324 35433 35471 35509 35620 35646 35748 35751 35765 35818 35987 36090 36240 36326 36460 36467 36476 36636 36793 37481 37552 38316 38993 39101 39674 40918 41297 43605 43911 44456 44844 45178 45238 45369 45381 45394 45407 45438 45445 45457 45499 45591 45740 45787 45834 45836 46012 46116 46189 46269 46329 46347 46376 46422-46423 46495 46538 46546 46676 46687 46702 46744 46753 46763 46918 46970 47012 47032 47514 48011 48127 48196 48272 48318 48703 48723 48735 48917 48933 48948 49017 49036 490481.5062136169708525e-19 1.7003137259100215e-19https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/402/575?format=asciiInfrareddefaultJ/MNRAS/402/575/table2Properties of the 132 MG candidatesrecnoRecord number assigned by the VizieR team.
