Hydrogen mass fraction (upper panel), helium mass fraction (second panel from top) and metallicity (two lower panels) at the surface of the 0.8 (dashed-short), 0.9 (dashed-long) and 1.0 M⊙ (continuous) Zinit = 0.014 models as a function of age. Filled diamonds indicate the end of the main sequence phase. Filled circles on the 1 M⊙ tracks locate the solar model at an age of 4.57 Gyr.
