cds-question@unistra.frchemical-abundancesspectroscopyExtremely metal-poor stars contain the fossil records of the chemical composition of the early Galaxy and it is important to compare Ca abundance with abundances of other light elements, that are supposed to be synthesized in the same stellar evolution phases. The NLTE profiles of the calcium lines were computed with a modified version of the program MULTI, which allows a very good description of the radiation field.2012A&A...541A.143Shttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/541/A143CatalogResearchIsServedByTAP VizieR generic servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/541/A143https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/541/A143http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/541/A143https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/541/A143https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/541/A143http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/541/A143GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapdefaultJ/A+A/541/A143/resultsNLTE corrections for the grid of models with [Fe/H]=(0.0,-1.0,-2.0,-3.0,-3.5) (tables A1--A5 of paper)T[4750/7000] TemperatureKphys.temperatureintIonSpecies (Ca I or Ca II)phys.atmol.ionStagecharrecnoRecord number assigned by the VizieR team.
