cds-question@unistra.frlate-type-starsstellar-atmosphereschemical-abundancesline-intensitiesAn extensive profile-fitting analysis was performed for the Li(+Fe) 6707-6708{AA} feature of nearby 160 F-K dwarfs/subgiants (including 27 planet-host stars) in the Galactic disk (7000K>~Teff>~5000K, -1<~[Fe/H]<~+0.4), in order to establish the photospheric lithium abundances of these stars. The non-LTE effect (though quantitatively insignificant) was taken into account based on our statistical equilibrium calculations, which were carried out on an adequate grid of models. Our results confirmed most of the interesting observational characteristics revealed by recently published studies, such as the bimodal distribution of the Li abundances for stars at Teff>~6000K, the satisfactory agreement of the upper envelope of the A(Li) vs. [Fe/H] distribution with the theoretical models, the existence of a positive correlation between A(Li) and the stellar mass, and the tendency of lower lithium abundances of planet-host stars (as compared to stars without planets) at the narrow ``transition'' region of 5900K>~Teff>~5800K. The solar Li abundance derived from this analysis is 0.92 (H=12.00), which is by 0.24dex lower than the widely referenced standard value of 1.16.2005PASJ...57...45Thttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/PASJ/57/45CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/PASJ/57/27 : Atmospheric parameters of nearby F-K stars (Takeda+, 2005)J/PASJ/57/65 : CNO abundances of solar-type stars (Takeda+, 2005)J/PASJ/57/109 : Late-G giants abundances (Takeda+, 2005)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/PASJ/57/45https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/PASJ/57/45http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/PASJ/57/45https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/PASJ/57/45https://vizier.iucaa.in/viz-bin/votable?-source=J/PASJ/57/45http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/PASJ/57/45GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/PASJ/57/45/table1 (Stellar parameters and the results of the abundance analysis)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/PASJ/57/45/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/PASJ/57/45/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/PASJ/57/45/table1?GETtext/xml+votable180.050000true1.565892258.43672810.0055555555555555566/679 684 706 819 934 1341 2472 2476 2650 2923 3006 3020 3036 3118 3639 4468 4808 4839 4854 5009 5154 5266 5304 5339 5522 5531 5670 5718 5836 6056 6130 6308 6926 7238 7390 8476 8602 8716 8788 8790 8843 8845 9072 9125 9403 9476 9835 9843 10375 10598 10812 10899 11290 11620 11691 11773 12146 12337 12464 12890 12899 12944 13474 13620 14146 14180 14459 14539 14573 15030 15118 15174 15356 15620 15962 16069 16883 17171 17425 17576 17588 17606 17730 17860 18002 18139 18614 18821 19312 19323 19585 20145 20278 20440 20446 21696 21864 22036 22120 22180 22300 22594 22654 22878 23013 23190 23201 23230 23974 24019 24151 24160 24212 24920 24924 24951 25198 25407 25862 25869 26462 26521 26575 26676 26963 26975 27088 28122 28494 28605 28664 28763 29541 30576 30665 30798 30848 30965 30989 31478 31751 32067 32192 32619 32645 36564 36664 36697 36723 36762 40442 40692 40716 40823 40932 44243 44879 48105 49114https://cdsarc.cds.unistra.fr/viz-bin/moc/J/PASJ/57/45?format=asciidefaultJ/PASJ/57/45/table1Stellar parameters and the results of the abundance analysisrecnoRecord number assigned by the VizieR team.
