A multi-epoch kinematic study of the remote dwarf spheroidal galaxy Leo
  II
  We conducted a large spectroscopic survey of 336 red giants in the direction
of the Leo II dwarf galaxy using Hectochelle on the MMT, and conclude that 175
of them are members based on their radial velocities and surface gravities. Of
this set, 40 stars have never before been spectroscopically observed. The
systemic velocity of the dwarf is 78.3+-0.6 km/s with a velocity dispersion of
7.4+-0.4 km/s . We identify one star beyond the tidal radius of Leo II but find
no signatures of uniform rotation, kinematic asymmetries, or streams. The stars
show a strong metallicity gradient of -1.53+-0.10 dex/kpc and have a mean
metallicity of -1.70+-0.02 dex. There is also evidence of two different
chemodynamic populations, but the signal is weak. A larger sample of stars
would be necessary to verify this feature.
