cds-question@unistra.frgalaxiescatalogsh-ii-regionschemical-abundancesgalaxy-classification-systemsWe examine the possible dependence of the radial oxygen abundance distribution on non-axisymmetrical structures (bar/spirals) and other macroscopic parameters such as the mass, the optical radius R25, the color g-r, and the surface brightness of the galaxy. A sample of disk galaxies from the third data release of the Calar Alto Legacy Integral Field Area Survey (CALIFA DR3) is considered. We adopted the Fourier amplitude A2 of the surface brightness as a quantitative characteristic of the strength of nonaxisymmetric structures in a galactic disk, in addition to the commonly used morphologic division for A, AB, and B types based on the Hubble classification. To distinguish changes in local oxygen abundance caused by the non-axisymmetrical structures, the multiparametric mass-metallicity relation was constructed as a function of parameters such as the bar/spiral pattern strength, the disk size, color index g-r in the Sloan Digital Sky Survey (SDSS) bands, and central surface brightness of the disk. The gas-phase oxygen abundance gradient is determined by using the R calibration We find that there is no significant impact of the non-axisymmetric structures such as a bar and/or spiral patterns on the local oxygen abundance and radial oxygen abundance gradient of disk galaxies. Galaxies with higher mass, however, exhibit flatter oxygen abundance gradients in units of dex/kpc, but this effect is significantly less prominent for the oxygen abundance gradients in units of dex/R25 and almost disappears when the inner parts are avoided (R>0.25R25). We show that the oxygen abundance in the central part of the galaxy depends neither on the optical radius R25 nor on the color g-r or the surface brightness of the galaxy. Instead, outside the central part of the galaxy, the oxygen abundance increases with g-r value and central surface brightness of the disk.2019A&A...623A...7Zhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/623/A7CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/A+A/594/A36 : CALIFA Survey DR3 list of galaxies (Sanchez+, 2016)J/A+A/595/A62 : CALIFA galaxies O/H and N/O slopes (Perez-Montero+, 2016)J/MNRAS/462/2715 : Oxygen abundance maps of CALIFA galaxies (Zinchenko+, 2016)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/623/A7https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/623/A7http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/623/A7https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/623/A7https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/623/A7http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/623/A7GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/623/A7/table1 (Adopted and derived properties of our target galaxies)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/623/A7/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/623/A7/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/623/A7/table1?GETtext/xml+votable180.050000true1.816064427.70806250.0055555555555555566/43 626 738 2641 4178 4342 4511 4667 4843 4850 5028 5332 5579 5593 7584 7824 8045 8458 8552 9622 9891 10025 10111 10113 10280 10380-10381 10566 10629 10661 10674 10705 10739-10740 11396 11832 13316 16788 17571 17747 17761 18069 18173 18779 18800 18854 18941 19267 19489 19537 19749 19954 19996 20193 20254 20279 20417 22654 22742 27748 28513 28579 29973 31628 32478 36793https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/623/A7?format=asciiOpticaldefaultJ/A+A/623/A7/table1Adopted and derived properties of our target galaxiesDistDistance (1)Mpcpos.distancefloatTypeMorphological type (2)src.morph.typecharrecnoRecord number assigned by the VizieR team.
