Li evolution from the stellar evolution model PARSEC. Two stars with the same metallicity and He content (Z = 0.002, Y = 0.252), the same initial Li abundance (A_Li = 2.8 dex), the stellar mass (M_i = 0.80 M_⊙), but different α-enhancements are compared. The red curves indicate the star with [α/Fe] = 0.4 dex while the black ones are for the star with [α/Fe] = 0 (solar-scaled). The dotted lines in both colours represent the evolution before the zero-age main sequence (ZAMS), and the solid lines indicate the evolution after. The panels from left to right are HR diagram, A_Li evolution with stellar age, and A_Li as a functionof log(g).
