From stellar spectra obtained with the MMT/Hectochelle spectrograph we identify seven likely members of Leo V. Five cluster near the Leo V center (R<3') and have a velocity dispersion of 2.4^+2.4^_1.4_km/s. The other two likely members lie near each other but far from the center (R~13'~700pc) and inflate the global velocity dispersion to 3.7^+2.3^_1.4_km/s.2009ApJ...694L.144Whttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/694/L144CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/MNRAS/397/1748 : Spectroscopic study of Segue 2 (Belokurov+, 2009)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJ/694/L144https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJ/694/L144http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJ/694/L144https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJ/694/L144https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJ/694/L144http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJ/694/L144GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/ApJ/694/L144/table1 (Hectochelle Spectroscopy of Leo V)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJ/694/L144/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJ/694/L144/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJ/694/L144/table1?GETtext/xml+votable180.050000true172.80504172.21433330.0055555555555555565/6750https://cdsarc.cds.unistra.fr/viz-bin/moc/J/ApJ/694/L144?format=asciiOpticaldefaultJ/ApJ/694/L144/table1Hectochelle Spectroscopy of Leo VrecnoRecord number assigned by the VizieR team.
