What heats the bright HII regions in I Zw 18?
Grazyna Stasinska, Daniel Schaerer
We have used the radiation field from a starburst population synthesis model appropriate for the brightest HII region of IZw 18 to perform a photoionization model analysis of this…
Wolf-Rayet galaxies as probes of young stellar systems
Daniel Schaerer
Wolf-Rayet (WR) galaxies provide detailed information on massive star populations in starbursts and thereby represent ideal objects to determine accurate ages for young systems, to…
Determining Star Formations Rates: Methods and Uncertainties
Daniel Schaerer
Methods for the determination of star formation rates (SFR) from integrated populations are reviewed. We discuss the assumptions and underlying uncertainties (e.g. IMF slope, M_up,…
On the origin of [OIV] emission in Wolf-Rayet galaxies
Daniel Schaerer, Grazyna Stasinska
We propose that the emission of the high excitation [OIV] line observed with ISO in NGC 5253 and II Zw 40 is due to the presence of hot Wolf-Rayet (WR) stars in these objects. We c…
