Scientific paper

In this second in a series of papers on the nature of classical H II regions in the Magellanic Clouds I investigate the properties of the underlying stellar content of the nebulae. Particular emphasis is placed on identifying and classifying the ionizing source(s) for each H II region. With the exception of the LMC H II regions DEM 20 and DEM 8c, I find that all of the objects in this sample are ionized by more than one O or B star. Even the faintest H II regions reflect the formation of a handful of massive, albeit early B type, stars. Typically, one star accounts for 60% - 70% of the ionizing photons and 2 - 5 less massive stars provide the remaining 30% - 40%. From the statistics of the hottest stars in these H II regions, and from considering all the blue stars contained within each region, the distribution of massive stars with spectral type is consistent with results found in similar galactic H II regions.
