HII Regions Feeding the Interstellar Medium in M 83
We analyse the internal dynamics of star-forming H ii regions and their efficiency in interacting with the ISM. We have selected the nearby (4.5 Mpc) spiral galaxy M 83, and from GHαFaS Fabry-Perot observations of the central 3.4' × 3.4' region, extracted the integrated Hα emission-line profiles of a sample of 136 isolated H ii regions.
