On the kinematic age of brown dwarfs: radial velocities and space motions of 43 nearby L dwarfs. Seifahrt A., Reiners A., Almaghrbi K.A.M., Basri G. <Astron. Astrophys. 512, A37 (2010)> =2010A&A...512A..37S
ADC_Keywords: Stars, dwarfs ; Parallaxes, trigonometric; Radial velocities ; Stars, late-type ; Space velocities ; Stars, distances Keywords: stars: low-mass - brown dwarfs - stars: kinematics and dynamics - techniques: radial velocities Abstract: We present radial velocity measurements of a sample of L0-L8 dwarfs observed with VLT/UVES and Keck/HIRES. We combine these measurements with distance and proper motion from the literature to determine space motions for 43 of our targets. We identify nine candidate members of young moving groups, which have ages of 50-600Myr according to their space motion. File Summary:
