Up: Li-rich giants: A

1. Introduction

In Gregorio-Hetem et al. (1993) and Castilho (1995) the far-infrared emission of Li-rich giants (LRG) was analyzed, based on data from the IRAS Point Source Catalog for the sample of LRG discovered by Brown et al. (1989, hereafter BSLD). BSLD obtained coudé spectra for 644 giants, and found 9 new LRG (tex2html_wrap_inline1046), which corresponds to tex2html_wrap_inline10481.5tex2html_wrap_inline1050 of their sample of G-K giants. They also found 8 stars with tex2html_wrap_inline1054 (tex2html_wrap_inline1056 of their sample).

In terms of IRAS colours the distribution of LRG is different from that of Li-normal giants. A large number of LRG are found within the "box" -0.7 < [25-12] < -0.3 and 0.0 < [60-25] < 0.25 as shown by Gregorio-Hetem et al. (1993) (these colours are defined by: tex2html_wrap_inline1062), where tex2html_wrap_inline1064, 25, and tex2html_wrap_inline1066).

Following the criterion of flux ratios given above, we have selected 280 candidates from the IRAS PSC and started an all sky survey of these stars (Barbuy et al. 1995, 1996). In this paper results of this survey are presented.

In Sect. 2 (click here) the selection criterion and the observations are described. In Sect. 3 (click here) the results are presented and discussed.
