WOLF-RAYET PHENOMENA IN MASSIVE STARS AND STARBURST GALAXIES
Abstract:
We study the properties of the young population of NGC 604 and find evidences for 1-2 Myr differences between different regions. Four of the eleven WR stars in NGC 604 are found to have wide Halpha emission lines. None of the WR stars is located within knots of high density, high excitation gas, as opposed to some of the O-type stars.
