Abstract
We analyze longslit spectral observations of fourteen Wolf-Rayet galaxies from the sample of Schaerer, Contini & Pindao (1999). All 14 galaxies show broad Wolf-Rayet emission in the blue region of the spectrum, consisting of a blend of NIII�4640, CIII�4650, CIV�4658, and HeII�4686 emission lines, which is a spectral characteristic of WN stars. Broad CIV�5808 emission, termed the red bump, is detected in 9 galaxies and CIII�5996 is detected in 6 galaxies. These emission features are due to WC stars. We derive the numbers of late WN and early WC stars from the luminosity of the blue and red bumps, respectively. � (. . :.
