cds-question@unistra.frastronomical-modelsstellar-atmospheresstellar-evolutionary-modelsstellar-populationsspectroscopyultraviolet-astronomyUsing new sets of stellar evolution models at very low metallicities (Z=10^-7^; 10^-5^) and previously published grids we examine spectral properties of the ionising continua, the Lyman-break, and the Ly{alpha} and He1640 recombination lines in starbursts. The metallicity dependence of these properties, especially the transition from primordial galaxies (Population III) to currently observed metallicities, is examined for various IMFs and star formation histories.2003A&A...397..527Shttps://cdsarc.cds.unistra.fr/viz-bin/cat/VI/109CatalogResearchIsServedByTAP VizieR generic servicerelated-tohttp://webast.ast.obs-mip.fr/sfr/ : Models homepagehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=VI/109https://vizier.iucaa.in/viz-bin/VizieR-2?-source=VI/109http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=VI/109https://vizier.cds.unistra.fr/viz-bin/votable?-source=VI/109https://vizier.iucaa.in/viz-bin/votable?-source=VI/109http://vizieridia.saao.ac.za/viz-bin/votable?-source=VI/109GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapUVdefaultVI/109/initialInitial parameters of the modelsrecnoRecord number assigned by the VizieR team.
