cds-question@unistra.frgalaxiesh-ii-regionschemical-abundancesvisible-astronomyWe here present the results from a detailed analysis of nebular abundances of commonly observed ions in the collisional ring galaxy Cartwheel using the Very Large Telescope (VLT) Multi-Unit Spectroscopic Explorer (MUSE) dataset. The analysis includes 221 HII regions in the star-forming ring, in addition to 40 relatively fainter Ha-emitting regions in the spokes, disk and the inner ring. The ionic abundances of He, N, O and Fe are obtained using the direct method (DM) for 9, 20, 20, and 17 ring HII regions, respectively, where the S++ temperature-sensitive line is detected. For the rest of the regions, including all the nebulae between the inner and the outer ring, we obtained O abundances using the strong-line method (SLM). The ring regions have a median 12+log(O/H)=8.19+/-0.15, log(N/O)=-1.57+/-0.09 and log(Fe/O)=-2.24+/-0.09 using the DM. Within the range of O abundances seen in the Cartwheel, the N/O and Fe/O values decrease proportionately with increasing O, suggesting local enrichment of O without corresponding enrichment of primary N and Fe. The O abundances of the disk HII regions obtained using the SLM show a well-defined radial gradient. The mean O abundance of the ring HII regions is lower by ~0.1dex as compared to the extrapolation of the radial gradient. The observed trends suggest the preservation of the pre-collisional abundance gradient, displacement of most of the processed elements to the ring, as predicted by the recent simulation by Renaud et al. (2018MNRAS.473..585R), and post- collisional infall of metal-poor gas in the ring.2022MNRAS.514.1689Zhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/514/1689CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/514/1689https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/514/1689http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/514/1689https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/514/1689https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/514/1689http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/514/1689GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/514/1689/table (Fluxes of principal emission lines)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/514/1689/table?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/514/1689/table?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/514/1689/table?GETtext/xml+votable180.050000true9.4172067-33.708321940.0055555555555555566/35576https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/514/1689?format=asciiOpticaldefaultJ/MNRAS/514/1689/tableFluxes of principal emission lines[FeIII/H]?
