Evolution of Li in FGK dwarf stars J/A+A/654/A137 ivo://CDS.VizieR/J/A+A/654/A137 doi:10.26093/cds/vizier.36540137 CDS Llorente de Andres F. Chavero C. de la Reza R. Roca-Fabrega S.,Cifuentes C. 2022-09-21T08:28:12Z 2021-10-22T10:21:38Z CDS support team CDS, Observatoire de Strasbourg, 11 rue de l'Universite, F-67000 Strasbourg, France cds-question@unistra.fr dwarf-stars chemical-abundances We investigate two topics regarding solar mass FGK-type stars, the lithium rotation connection (LRC) and the existence of the "lithium desert". We determine the minimum critical rotation velocity (vsini) related with the LRC separating slow from rapid stellar rotators, as being 5km/s. This value also split different stellar properties. For the first time we explore the behaviour of the LRC for some stellar associations with ages between 45Myr and 120Myr. This allows us to study the LRC age dependence at the beginning of the general spin down stage for low mass stars, which starts at ~30-40Myr. We find that each stellar group presents a characteristic minimum lithium (Li) depletion connected to a specific large rotation velocity and that this minimum changes with age. For instance, this minimum changes from ~50km/s to less than 20km/s in 200Myr. Regarding the lithium desert, it was described as a limited region in the A(Li)-Teff map containing no stars. Using Teff from Gaia DR2 we detect 30 stars inside and/or near the same box defined originally as the Li desert. Due to their intrinsic Teff errors some of these stars may be inside or outside the box, implying a large probability that the box contains several stars. Considering this last fact the "lithium desert" appears to be more a statistical distribution fluctuation than a real problem. 2021A&A...654A.137L https://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/654/A137 Catalog Research IsServedBy TAP VizieR generic service IsServedBy Conesearch service https://cds.unistra.fr/vizier-org/licences_vizier.html https://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/654/A137 https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/654/A137 http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/654/A137 https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/654/A137 https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/654/A137 http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/654/A137 GET text/xml+votable https://tapvizier.cds.unistra.fr/TAPVizieR/tap Cone search capability for table J/A+A/654/A137/table1 (Parameters of the stellar (MS stars)) https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/654/A137/table1? https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/654/A137/table1? http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/654/A137/table1?
