LI-RICH GIANTS - A SURVEY BASED ON IRAS COLORS

In a previous work we studied the IRAS colours of knows Li-rich red gi ants and showed that they have flux ratios F-12/F-25 and F-25/F-60 in well defined ranges. By using this result as a selection criterion, we prepared a list of 280 IRAS Point Source candidates to be Li-rich gia nt stars. Up to the present we have obtained spectra for 57% of our ta rget list. We identified five stars showing a strong LiI 670.079 mn li ne and six ones with a Li line of medium strength. Most of the candida tes show features typical of normal giants having circumstellar dust, as indicated by their IRAS colours.
