cds-question@unistra.frpre-main-sequence-starsstellar-evolutionary-modelsWhile MLT-alpha^2D^ models are not available for lower metallicities, we extend to lower Z the NEMO-FST models, under the hypothesis that in such a way we are simulating the results of MLT-alpha^2D^ models also at smaller Z. We use standard stellar computation techniques in which the atmospheric boundary conditions are derived making use of model atmosphere grids. This allows us to take into account the non greyness of the atmosphere, but adds a new parameter to the stellar structure uncertainty, namely the efficiency of convection in the atmospheric structure, if convection is computed in the atmospheric grid by a model different to the model adopted for the interior integration.2009A&A...496..223Dhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/496/223CatalogResearchIsServedByTAP VizieR generic servicerelated-toVI/109 : Population Synthesis Models at very low Z (Schaerer, 2003)VI/113 : Evolutionary models of Population II stars (Cariulo+, 2004)J/A+A/361/1023 : Evolution models for {alpha}-enhanced stars (Salasnich+ 2000)J/A+AS/141/371 : Low-mass stars evolutionary tracks+isochrones (Girardi+, 2000)J/A+A/484/815 : Scaled solar tracks and isochrones (Bertelli+, 2008)J/A+A/494/209 : Pre-main sequence evolutionary tracks (Landin+, 2009)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/496/223https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/496/223http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/496/223https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/496/223https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/496/223http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/496/223GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapdefaultJ/A+A/496/223/tracksEvolutionary tracksrecnoRecord number assigned by the VizieR team.
