The impact of mass loss rate on internal abundance profiles for 0.80 M_⊙ models. A model without mass loss and models with five mass loss rates from 10^-14 M_⊙ yr^-1 to 10^-12 M_⊙ yr^-1 are shown and are identified in the figure. The internal concentration profiles are shown just before turnoff near 11.5 Gyr. Atomic diffusion affects mainly the outer 10^-2 of the stellar mass. Conventions are similar to those of Fig. 3.
