cds-question@unistra.frh-ii-regionssupernovaeSpectral modelling of typeII supernova atmospheres indicates a clear dependence of metal line strengths on progenitor metallicity. This dependence motivates further work to evaluate the accuracy with which these supernovae can be used as environment metallicity indicators. To assess this accuracy we present a sample of type II supernova host HII-region spectroscopy, from which environment oxygen abundances have been derived. These environment abundances are compared to the observed strength of metal lines in supernova spectra. Combining our sample with measurements from the literature, we present oxygen abundances of 119 host HII regions by extracting emission line fluxes and using abundance diagnostics. These abundances are then compared to equivalent widths of FeII 5018{AA} at various time and colour epochs. Our distribution of inferred type II supernova host HII-region abundances has a range of ~0.6dex. We confirm the dearth of type II supernovae exploding at metallicities lower than those found (on average) in the Large Magellanic Cloud. The equivalent width of FeII 5018{AA} at 50 days post-explosion shows a statistically significant correlation with host HII-region oxygen abundance. The strength of this correlation increases if one excludes abundance measurements derived far from supernova explosion sites. The correlation significance also increases if we only analyse a "gold" IIP sample, and if a colour epoch is used in place of time. In addition, no evidence is found of a correlation between progenitor metallicity and supernova light-curve or spectral properties - except for that stated above with respect to FeII 5018{AA} equivalent widths - suggesting progenitor metallicity is not a driving factor in producing the diversity that is observed in our sample. This study provides observational evidence of the usefulness of typeII supernovae as metallicity indicators. We finish with a discussion of the methodology needed to use supernova spectra as independent metallicity diagnostics throughout the Universe.2016A&A...589A.110Ahttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/589/A110CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/589/A110https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/589/A110http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/589/A110https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/589/A110https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/589/A110http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/589/A110GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/589/A110/tableab (SN and host galaxy data (table A1) and HII region abundances and SN pEWs (table B1))https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/589/A110/tableab?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/589/A110/tableab?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/589/A110/tableab?GETtext/xml+votable180.050000true64.3725-62.78444440.0055555555555555566/34 37 43 664 807 4182 4381 4410 4490 8306 8484 8700 12298 12471 16441 16479 16652 17001 17509 17637 17795 17835 18398 18405 18795 18895 19104 19536 19584 19616 20865 21047 21953 22613 22751 24170 24225 24873 24915 25051 25079 25438 25599 25645 25742 26191 26234 26263 26303 26433 26535 26667 27109 27588 27604 27712 27736 27840 28204 28346 29348 30036 30194 31107 33228 33795 34361 34777 35071 35313 35993 36210 36377 36489 36785 36799 36811 36827 36908 37436 37582 38623 38786 38817 38956 39108 40218 40267 40527 40531 40659 40819 40847 40939 43233 43302 43325 43473 43942 44726 45433 45711 46004 46041 46512 46568 47028 47187 47386 47460 47564 48661 48665 49092 49097https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/589/A110?format=asciidefaultJ/A+A/589/A110/tableabSN and host galaxy data (table A1) and HII region abundances and SN pEWs (table B1)recnoRecord number assigned by the VizieR team.
