cds-question@unistra.frh-ii-regionsspectroscopychemical-abundancesWe present deep spectroscopy of a large sample of low-metallicity emission-line galaxies. The main goal of this study is to derive element abundances in these low-metallicity galaxies. We analyze 121 VLT spectra of HII regions in 46 low-metallicity emission-line galaxies. Of these spectra 83 are archival VLT/FORS1+UVES spectra of HII regions in 31 low-metallicity emission-line galaxies that are studied for the first time with standard direct methods to determine the electron temperatures, the electron number densities, and the chemical abundances.2011A&A...529A.149Ghttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/529/A149CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/A+A/462/535 : Low-metallicity HII regions and galaxies (Yin+, 2007)J/A+A/464/885 : Abundances in 53 HII regions (Guseva+, 2007)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/529/A149https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/529/A149http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/529/A149https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/529/A149https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/529/A149http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/529/A149GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/529/A149/table1 (HII regions and galaxies observed with the VLT)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/529/A149/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/529/A149/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/529/A149/table1?GETtext/xml+votable180.050000true7.8925-2.1550.0055555555555555566/38 17725 17771 17816 17865 18027 18053 18198 18793 18858 24696 25169 26142 26821 27457 29718 33304 33317 34243 34426 38821 39602 40124 43420 43754 43845 43874 44236 46522 46786 46790 47701https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/529/A149?format=asciiOpticaldefaultJ/A+A/529/A149/table1HII regions and galaxies observed with the VLTrecnoRecord number assigned by the VizieR team.
