cds-question@unistra.frstellar-associationschemical-abundancesline-intensitiesOur study is a follow-up of the SACY project, an extended high spectral resolution survey of more than two thousand optical counterparts to X-ray sources in the southern hemisphere targeted to search for young nearby association. Nine associations have either been newly identified, or have had their member list revised. Groups belonging to the Sco-Cen-Oph complex are not considered in the present study. These nine associations, with ages of between about 6Myr and 70Myr, form an excellent sample to study the Li depletion in the pre-main sequence (PMS) evolution. In the present paper, we investigate the use of Li abundances as an independent clock to constrain the PMS evolution. Using our measurements of the equivalent widths of the Li resonance line and assuming fixed metallicities and microturbulence, we calculated the LTE Li abundances for 376 members of various young associations. In addition, we considered the effects of their projected stellar rotation.2009A&A...508..833Dhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/508/833CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/A+A/460/695 : Search for Associations Containing Young stars (Torres+, 2006)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/508/833https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/508/833http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/508/833https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/508/833https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/508/833http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/508/833GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/508/833/tables (Li abundances determined for all high probability members (tables 3-11 of the paper))https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/508/833/tables?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/508/833/tables?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/508/833/tables?GETtext/xml+votable180.050000true34.35291728.7416670.0055555555555555566/102 129 601 719 765 784 940 1762 2374 2966 10203 12436 12770 13512 13674 15686 16393 16426 16853 16930 17288 17552 19163 20327 20491-20492 20505 20510 20528 20564 20610 20618 20636-20637 20650 20657 20706 21023 21050 21080 21082-21083 21094 21135 21145 21180 21217-21218 21296 21365 21386 21418 21422 21424 21436 21520 21763 22066-22067 22146 22581 22619 22773 22823 22856 22908 22964 23068 23094 23136 23140 23155 23272 23321 23385 23395 23895 24580 24608 24716 24763 25113 26133 27392 28746 28784 28810 29569 29993 29999 30477 30826 31104 32836 32844 32937 33050 33116 33268 33312 33361 33500 33583 33694 33707 33850 33937 33996 34008 34012 34047 34050 34054 34066 34073-34074 34099 34102 34126 34138 34140 34165 34203 34206 34244-34245 34269 34290 34338 34385 34423 34436 34450 34586 34683 34757 34781 34790 34823 34825 34829-34830 34886 34930 35018 35077 35123 35497 35640 35861 35929 36130 36308 36346 36487 36578 36686 36713 36884 36899 36907 36948 36969 37006 37010 37012-37013 37065 37075 37078 37120 37125 37172-37174 37272 37297 37302 37414 37419 37494 37542 37628 37637 37652 37664 37678 37683 37688 37695 37730 37745 37781 37783 37785 37787-37788 37790-37791 37808-37809 37811 37817 37838 37970 38347 38359 38363 38382 38440 38454 38472 38522 38555 38593 38687 38742 38936 38950 38969 38985-38986 39044 39051 39122-39123 39208 39310 39450 39489 39524 39579 39625 39634 39829 39851 40184 40596 40904 40977 41128 41130-41131 41139 41158 41295 41472 41481 41484 41505 41526 41528 41553 41600 41798 42096 42242 42272 43065 43571 43670 43677 43704 44439 45072 45101 45208 45336 45351 45382 45475 45538 45544 45607 45746 45927 45964 46383 46788 46922 47120 47125 47205 47287 47366 47626 47777 47863 48038 48045 48061 48263 48274 48559 48651 48672 48905https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/508/833?format=asciidefaultJ/A+A/508/833/tablesLi abundances determined for all high probability members (tables 3-11 of the paper)recnoRecord number assigned by the VizieR team.
