Same representation as in Fig. 4, but for stars of the AB Dor association with an age of ∼120 Myr (panel a) and of the open cluster Pleiades with an age of 125 Myr (panel b). As in Fig. 4, the distribution shows that the few more Li depleted stars are K-dwarf stars. The spectral types are indicated for stars with v sin i > 30. Intruder stars in AB Dor are represented by open squares. The values of the Pleiades stars are from Barrado et al. (2016)
