For 41 objects the A(Li) here presented corresponds to the first measurement. We have measured the equivalent widths of the 6708 {AA} lithium feature in high-resolution spectroscopic images (R~80000), obtained at the Observatorio Astrofisico 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+/-52 K, A(Li)=1.86+/-0.07 dex) lies inside the so-called lithium desert in the A(Li)-T_eff_ plane. The other object, BD+28 4515, has an A(Li)=3.05+/-0.07 dex, which is the highest of our sample and compatible with the expected abundances of relatively young stars.2015MNRAS.451.4368Lhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/451/4368CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/A+A/530/A138 : Geneva-Copenhagen survey re-analysis (Casagrande+, 2011)J/MNRAS/444/2251 : G0-G3 main-sequence stars with V<15 (Lopez-Valdivia+, 2014)J/ApJ/865/68 : Abundances for 79 Sun-like stars within 100pchttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/451/4368https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/451/4368http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/451/4368https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/451/4368https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/451/4368http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/451/4368GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/451/4368/table1 (Physical parameters and Li abundance of the stellar sample)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/451/4368/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/451/4368/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/451/4368/table1?GETtext/xml+votable180.050000true14.822058161.91009470.0055555555555555566/1070 3161 3258 3309 3312 3330 3609 3714 4871 8635 8918 8955 8995 9045 9056 9112 9295 9345 10408 11228 12621 12634 13087 13395 13576 14247 14249 14253 14411 14414 14417 14441 14479 14649 15399 15962 18696 20078 20127 22990 23661 24299 24373 25977 28156 30503 31912 32511 32585 49114https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/451/4368?format=asciidefaultJ/MNRAS/451/4368/table1Physical parameters and Li abundance of the stellar samplerecnoRecord number assigned by the VizieR team.
