Exciting stars of H II regions in the Large Magellanic Cloud. Israel, F. P. ; Koornneef, J. Abstract We present UV observations in the wavelength range A of the star clusters in several H ii regions belonging to the Large Magellanic Cloud (LMC). The early type stars (spectral types 0, B, and A) in these clusters are characterized by a moderately steep luminosity function that is close to the Salpeter-Sandage initial luminosity function for early type stars. We confirm the general shape of the reddening law as derived earlier by the use of a different method. The total luminosity of the 30 Dor star cluster is about 108 L0, while the luminosities of the other observed regions are 0.5-1.0 x 10 L0. The central object R136 contributes significantly to the excitation of 30 Dor.
