Combining these with published rotation periods, the connection between lithium depletion and rotation is studied in unprecedented detail. At T_eff_<5500K there is a strong relationship between faster rotation and less Li depletion, although with a dispersion larger than measurement uncertainties. Components of photometrically identified binary systems follow the same relationship. A correlation is also established between faster rotation rate (or smaller Rossby number), decreased Li depletion and larger stellar radius at a given T_eff_. These results support models where star-spots and interior magnetic fields lead to inflated radii and reduced Li depletion during the pre-main-sequence (PMS) phase for the fastest rotators. However, the data are also consistent with the idea that all stars suffered lower levels of Li depletion than predicted by standard PMS models, perhaps because of deficiencies in those models or because saturated levels of magnetic activity suppress Li depletion equally in PMS stars of similar T_eff_ regardless of rotation rate, and that slower rotators subsequently experience more mixing and post-PMS Li depletion.2021MNRAS.500.1158Jhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/500/1158CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toI/345 : Gaia DR2 (Gaia Collaboration, 2018)J/A+A/575/A120 : DANCe study of M35 (NGC 2168) (Bouy+, 2015)J/ApJ/695/679 : Stellar rotation in M35 (Meibom+, 2009)J/AJ/156/37 : Photometry & Li abund. of cool dwarfs in M35https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/500/1158https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/500/1158http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/500/1158https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/500/1158https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/500/1158http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/500/1158GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/500/1158/table1 (Targets in M35, giving the information from which the targets were selected, measurements from the spectra and kinematic membership probability)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/500/1158/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/500/1158/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/500/1158/table1?GETtext/xml+votable180.050000true91.77508524.190860.0055555555555555566/24338-24339 24344-243454.318361990336016e-20 6.118840631666147e-19https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/500/1158?format=asciiOpticalInfrareddefaultJ/MNRAS/500/1158/table1Targets in M35, giving the information from which the targets were selected, measurements from the spectra and kinematic membership probabilityrecnoRecord number assigned by the VizieR team.
