cds-question@unistra.fropen-star-clustersdwarf-starsproper-motionsThe proper motion measurements for 142 previously known L and T dwarfs are presented. From this sample we identify and discuss eight high-velocity L dwarfs. We also find four new wide common proper motion binaries/multiple systems. Using the moving cluster methods we have also identified a number of L dwarfs that may be members of the Ursa Major (age~400Myr), the Hyades (age~625Myr) and the Pleiades (age~125Myr) moving groups.2008MNRAS.384.1399Jhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/384/1399CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toII/246 : 2MASS All-Sky Catalog of Point Sources (Cutri+ 2003)J/AJ/123/3409 : SDSS M, L, and T dwarfs (Hawley+, 2002)J/ApJ/564/421 : Spectra of T dwarfs.
