Radiative accelerations and gravity at four different ages in a 0.8 M_⊙ model with Ṁ = 10^-12 M_⊙ yr^-1. The vertical lines indicate the position of the bottom of the SCZ. The ages are identified in the figure.

Abundance profiles at four different ages in a 0.8 M_⊙ model with Ṁ = 10^-12 M_⊙ yr^-1 and an initial metallicty of Z₀ = 0.00017. The vertical lines indicate the position of the bottom of the SCZ. The ages are identified in the figure.

Abundance profiles for the model without mass loss and for mass loss rates, from Ṁ = 10^-14 M_⊙ yr^-1 to Ṁ = 10^-12 M_⊙ yr^-1 in a 0.8 M_⊙ model and an initial metallicty of Z₀ = 0.00017. The internal concentration profiles are shown just before turnoff near 11.5 Gyr. The vertical lines indicate the position of the bottom of the SCZ. The mass loss rates are identified in the figure.

Evolution of surface abundances for the model without mass loss (dotted line) and for mass loss rates, from Ṁ = 10^-15 M_⊙ yr^-1, to Ṁ = 10^-12 M_⊙ yr^-1 in a 0.8 M_⊙ model and an initial metallicty of Z₀ = 0.00017. One cannot distinguish the curves for the model without mass loss from those for the model with Ṁ = 10^-15 M_⊙ yr^-1. The mass loss rates are identified in the figure.
