  • We present VLT imaging and spectroscopy of M83, revealing a large disk Wolf-Rayet population. The observed WC to WN ratio is ∼ 1.3, extending previous Local Group results to higher metallicity, and is significantly higher than current evolutionary predictions at high metallicity. Late subtypes dominate the WC population, arguing in favour of metallicity-dependent WR winds, of application to the hardness of Lyman continuum fluxes from young starbursts. Finally, source #74 is identified as a… CONTINUE READING
