cds-question@unistra.frgalaxiesspectroscopyradial-velocitygalaxy-kinematicsThe correlation between the breaks in the metallicity distribution and the corotation radius of spiral galaxies has been already advocated in the past and is predicted by a chemodynamical model of our Galaxy that effectively introduces the role of spiral arms in the star formation rate. In this work, we present photometric and spectroscopic observations made with the Gemini Telescope for three of the best candidates of spiral galaxies to have the corotation inside the optical disc: IC 0167, NGC 1042 and NGC 6907. We observed the most intense and well-distributed HII regions of these galaxies, deriving reliable galactocentric distances and oxygen abundances by applying different statistical methods. From these results, we confirm the presence of variations in the gradients of metallicity of these galaxies that are possibly correlated with the corotation resonance.2011MNRAS.412.1741Shttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/412/1741CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/412/1741https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/412/1741http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/412/1741https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/412/1741https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/412/1741http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/412/1741GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/412/1741/spectro (Information about the spectra observed in 2006 and 2005 for the 3 galaxies IC0167, NGC1042 and NGC6907)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/412/1741/spectro?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/412/1741/spectro?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/412/1741/spectro?GETtext/xml+votable180.050000true27.8195421.949810.0055555555555555566/697 36785 48665https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/412/1741?format=asciiOpticaldefaultJ/MNRAS/412/1741/spectroInformation about the spectra observed in 2006 and 2005 for the 3 galaxies IC0167, NGC1042 and NGC6907recnoRecord number assigned by the VizieR team.
