cds-question@unistra.frgalaxiesvisible-astronomyredshiftedchemical-abundancesWe have identified a sample of 41 low-mass high-oxygen abundance outliers from the mass-metallicity relation of star-forming galaxies measured by Tremonti et al. (2004ApJ...613..898T). These galaxies, which have 8.6<12+log(O/H)<9.3 over a range of -14.4>M_B_>-19.1 and 7.4<log(M_*_/M_{sun}_)<10, are surprisingly nonpathological. They have typical specific star formation rates, are fairly isolated, and, with few exceptions, have no obvious companions. Morphologically, they are similar to dwarf spheroidal or dwarf elliptical galaxies. We predict that their observed high oxygen abundances are due to relatively low gas fractions, concluding that these are transitional dwarf galaxies nearing the end of their star formation activity.2008ApJ...685..904Phttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/685/904CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toII/294 : The SDSS Photometric Catalog, Release 7 (Adelman-McCarthy+, 2009)J/ApJ/695/259 : Massive metal-poor galaxies from SDSS (Peeples+, 2009)J/ApJ/676/286 : Spectral templates for galaxies from 0.2 to 10um (Assef+,J/A+A/459/85 : O/H and gas densities in star-forming galaxies (Nagao+, 2006)J/A+A/448/955 : Abundances of emission galaxies in SDSS-DR3 (Izotov+, 2006)http://www.sdss.org/ : SDSS home pagehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJ/685/904https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJ/685/904http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJ/685/904https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJ/685/904https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJ/685/904http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJ/685/904GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/ApJ/685/904/table1 (Full sample of low-luminosity mass-metallicity outliers)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJ/685/904/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJ/685/904/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJ/685/904/table1?GETtext/xml+votable180.050000true193.9056-1.329860.0055555555555555566/4828 4987 5058 5554 5598 5665 5776 5779 6135 6216 7299 9206 9809 9891 10182 10911 10937 11179 11344 11433 11434 11830 17754 17773 18390 19988 25855 26088 26184 26208 26284 26309 26313 26341 26432 27045 27575 31406 31407 36787https://cdsarc.cds.unistra.fr/viz-bin/moc/J/ApJ/685/904?format=asciiOpticaldefaultJ/ApJ/685/904/table1Full sample of low-luminosity mass-metallicity outliersrecnoRecord number assigned by the VizieR team.
