ADC_Keywords: Galaxies, nearby ; Velocity dispersion ; Abundances, [Fe/H] Keywords: galaxies: dwarf - galaxies: individual (Leo II) - galaxies: kinematics and dynamics - galaxies: stellar content - galaxies: structure - Local Group Abstract: We present the projected velocity dispersion profile for the remote (d=233kpc) Galactic dwarf spheroidal (dSph) galaxy Leo II, based on 171 discrete stellar radial velocities that were obtained from medium-resolution spectroscopy using the FLAMES/GIRAFFE spectrograph at the European Southern Observatory, Chile. Description: In the framework of the ESO Large Program 171.B-0520(A) (principal investigator: G.F. Gilmore), which aims to elucidate the kinematic and chemical characteristics of Galactic dSphs, five fields in Leo II were observed using the FLAMES multiobject facility at ESO's Very Large Telescope.
