cds-question@unistra.frlate-type-starschemical-abundancesatomic-physicsWe perform non-LTE calculations of lithium in late-type stars for a wide range of stellar parameters, including quantum mechanical cross-sections for collisions with neutral hydrogen and the negative hydrogen ion. Non-LTE abundance corrections for the lithium resonance line at 670.7nm and the subordinate line at 610.3nm, are calculated using 1D MARCS model atmospheres spanning a large grid in effective temperature, surface gravity, and metallicity, and lithium abundance. The competing effects of ultraviolet over-ionization and photon losses in the resonance line govern the behaviour of the non-LTE effects with stellar parameters and lithium abundance. The size and sign of the non-LTE abundance corrections vary significantly over the grid for the 670.7nm line, but are typically positive and below 0.15dex for the 610.3nm line. The new collisional data play a significant role in determining the abundance corrections.2009A&A...503..541Lhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/503/541CatalogResearchIsServedByTAP VizieR generic servicerelated-toJ/PASJ/57/45 : Lithium abundances of F-K stars (Takeda+, 2005)J/A+A/503/545 : NGC 6397 Li depletion and Li-Na anti-correlation (Lind+, 2009)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/503/541https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/503/541http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/503/541https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/503/541https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/503/541http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/503/541GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapdefaultJ/A+A/503/541/table2Non-LTE abundance corrections and equivalent widths for the 670.7nm linerecnoRecord number assigned by the VizieR team.
