cds-question@unistra.frgalaxiesspectroscopyline-intensitiesvariable-starsWe present a catalogue of non-nuclear regions containing Wolf-Rayet stars in the metal-rich spiral galaxy M 83 (NGC 5236). From a total of 283 candidate regions identified using He II {lambda}4686 imaging with VLT-FORS2, Multi Object Spectroscopy of 198 regions was carried out, confirming 132 WR sources. From this sub-sample, an exceptional content of ~1035+/-300 WR stars is inferred, with N(WC)/N(WN) ~ 1.2, continuing the trend to larger values at higher metallicity amongst Local Group galaxies, and greatly exceeding current evolutionary predictions at high metallicity.2005A&A...439..265Hhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/439/265CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/439/265https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/439/265http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/439/265https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/439/265https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/439/265http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/439/265GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/439/265/tablea1 (Catalogue of sources with confirmed WR spectroscopic signatures in M83.)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/439/265/tablea1?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/439/265/tablea1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/439/265/tablea1?GETtext/xml+votable180.050000true204.1678333-29.85586110.005555555555555556Cone search capability for table J/A+A/439/265/tablea2 (Catalogue of sources with candidate WR signatures in M83, either from narrow-band imaging or for which MOS spectroscopy was ambiguous.)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/439/265/tablea2?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/439/265/tablea2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/439/265/tablea2?GETtext/xml+votable180.050000true204.183375-29.86308330.0055555555555555566/43881https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/439/265?format=asciiOpticaldefaultJ/A+A/439/265/table1FORS2 Multi Object Spectroscopy (MOS) observing log for M83.recnoRecord number assigned by the VizieR team.
