Analysis of the moderately Li-rich giant HD 146850.

CASTILHO B.V., BARBUY B. and GREGORIO-HETEM J.

Abstract (from CDS):

We report the identification of 3 Li-rich giants discovered in an ongoing survey based on IRAS colours. A detailed analysis of one of these, HD 146850, is presented here. High-resolution spectra were obtained for this star, using CASPEC at the 3.6m telescope of ESO. We derived the stellar parameters (Teff, log g, [M/H])=4000, 1.5, -0.3. A lithium abundance of ε(Li)=1.6 is found, whereas [C/Fe]∼0.0 and [N/Fe]~-0.1 indicating that no convective mixing has occurred. The abundances of oxygen [O/Fe]≃+0.1 and α-elements [Mg/Fe]=[Ti/Fe]=[Ca/Fe]≃0.0 suggest that we are dealing with a disk star, for which the radial velocity vr=42km/s is also moderate.
