Wolf-Rayet population in M83

DOI

We 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.

Cone search capability for table J/A+A/439/265/tablea1 (Catalogue of sources with confirmed WR spectroscopic signatures in M83.)

Cone 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.)
