| Description | We present the results of an analysis of seven faint K giants with strong Li lines, recently discovered during the Picodos Dias urvey, from high-resolution and high signal-to-noise-ratio spectra. The fundamental parameters of these stars, such as effective temperature, surface gravity, metallicity and microturbulence, were determined. We also obtained LTE abundances of Li and CNO elements and measured the$ ^{12}C/^{13}$C ratios by spectral synthesis using the lines of Li I (λ6104Â and λ6708 Â), $C_{2}$, CN, and [O I]. The studied Li K stars are found to be red giant branch stars with masses around $1M_{⊙}$. |
