Lithium and Lithium Depletion in Halo Stars on Extreme Orbits

We have determined Li abundances in 55 dwarfs and subgiants that are metal-poor (-3.6 < [Fe/H] < -0.7) and have extreme orbital kinematics. Our purpose is to examine the Li abundance in the Li plateau stars and its decrease in low-temperature, low-mass stars. For the stars in our sample we hav...
