Lithium EW as a function of the T_eff for the candidate members of Cha I. The red (large) dots identify the UVES stars. Most of the Li detections in UVES spectra have uncertainties associated to their EWs smaller than the data points. The GIRAFFE members identified by Sacco et al. (in prep.) with a T_eff determination are shown by the smaller blue dots. All the “L08-mem” are marked with a green circle. The solid line denotes the upper-envelope of the Pleiades distribution (crosses; Soderblom et al. 1993; Jones et al. 1996).
