Comparison of observed and modelled Li-rich AGB samples in the Milky Way and the Magellanic Clouds. The upper panel shows the Milky Way sample with effective temperature versus ⁷Li abundance, with T_eff errors of ±100K and ⁷Li abundance errors of ±0.3dex. The lower panel shows the Magellanic Cloud sample with T_eff errors of ±300K and ⁷Li abundance errors of ±0.5dex. The models with IGW mixing are all displayed on the left, while the models without IGW mixing are displayed on the right.
