Left panel: various chemical elements in the interior of a 1.3 M_⊙ solar metallicity star without rotation at the beginning (upper panel), middle (middle panel), and the terminal stage (bottom panel) of lithium enrichment. Right panel: The various diffusion coefficients (i.e. D_con: convective motion; D_th: thermohaline mixing; D_ST: Taylor-spruit dynamo; D_ES: meridional circulation; D_fim: flash-induced IGW mixing) in the interior of a 1.3 M_⊙ solar metallicity star with an initial rotation v_ini = 100 km/s at the beginning (upper panel), middle (middle panel), and the terminal stage (bottom panel) of lithium enrichment. Grey areas in the right panel represent the convection zone.
