We report on the determination of the lithium abundance [ A ( Li ) ] of 52 solar-like stars .
For 41 objects the A ( Li ) here presented corresponds to the first measurement .
We have measured the equivalent widths of the 6708 Å lithium feature in high-resolution spectroscopic images ( R \sim 80 000 ) , obtained at the Observatorio Astrofísico Guillermo Haro ( Sonora , Mexico ) , as part of the first scientific observations of the revitalized Lunar and Planetary Laboratory ( LPL ) Echelle Spectrograph , now known as the Cananea High-resolution Spectrograph ( CanHiS ) .
Lithium abundances were derived with the Fortran code MOOG , using as fundamental input a set of atmospheric parameters recently obtained by our group . With the help of an additional small sample with previous A ( Li ) determinations , we demonstrate that our lithium abundances are in agreement , to within uncertainties , with other works .
Two target objects stand out from the rest of the sample .
The star BD+47 3218 ( T _ { eff } = 6050 \pm 52 K , A ( Li ) = 1.86 \pm 0.07 dex ) lies inside the so-called lithium desert in the the A ( Li ) – T _ { eff } plane .
The other object , BD+28 4515 , has an A ( Li ) = 3.05 \pm 0.07 dex , which is the highest of our sample and compatible with the expected abundances of relatively young stars .
