A(Li) vs. T_eff in the field stars sample for which the mass was estimated. We plot in blue the MSTO stars (with T_eff > 6200 K), in orange the sub-giant stars, and in pink the giant stars. Li upper limits are shown with grey triangles. The curves are the predictions of the models of Lagarde et al. (2012) for 1.5 M_⊙, 2.0 M_⊙, and 3.0 M_⊙ with standard mixing (dashed lines) and with rotation-induced mixing and thermohaline instability (continuous lines). In the panels for [Fe/H]  < −0.5 dex and M≤2.2 M_⊙, we adopt the models at [Fe/H]  = −0.56, and in the other panels the models at [Fe/H]  = 0. The Li-rich stars with a mass determination are indicated with green stars.
