Abstract

We have studied the IRAS colours of Li-rich giants, concluding that they define a locus on the IRAS colours diagram (Gregorio-Hetem et al. 1993), within a box of colours −0.7<[25–12]<−0.3 and 0.0<[60–25]<+0.25. Such infrared colours indicate the presence of dust. We have up to now found 3 Li-rich giants, out of a sample of 30 candidates. We suggest that dusty cool AGB stars produce Li, and may be partly responsible for the Li enrichment in the Galaxy.
