(Left panel) Internal lithium profiles for 0.75 M_⊙ models with and without mass loss. Three models of different masses were added (colored curves) in order to verify the solution for the 0.75W1E-12 model. (Right panel) A comparison of diffusion (dotted and solid lines) and wind velocities (dashed lines identified in the figure) for the 0.75 M_⊙ models. The vertical solid line identifies the bottom of the surface convection zone. All models are shown at 10 Gyr. The left panel can be compared to Fig. 4 of Vauclair & Charbonnel (1995).
