Description
The discovery is reported of a new lithium super-rich carbon star, IY
Hya, and the Li abundance in three other carbon stars (T Sgr, WZ Cas and
WX Cyg), previously known as super Li-rich stars is derived. All these
stars show abundances in the range log N(Li) = 4.5 (i.e., 10 to 100
times higher than the present cosmic value). Two of them (WX Cyg and T
Sgr) present variations in the Li feature when compared with previous
studies.
