Scientific paper

During the 1995 March, 16 day Astro-2 mission of the Astro Space Shuttle observatory, we obtained far-UV spectra of the four WN stars WR 6 (WN5), WR 134 (WN6), WR 24 (WN7+a), and WR 40 (WN8) with the Hopkins Ultraviolet Telescope (HUT). These data, extending from 820 to 1840 A at a resolution of ~3 A, form the basis for the first systematic exploration of Wolf-Rayet star spectra from 1150 A to the Lyman limit. We identify the prominent emission lines in this spectral region and discuss their changes along the WN sequence. The spectrum of HD 5980, a former WN3 + WN4.5 SMC binary recently recognized as a luminous blue variable, is classified WN6/WN8 in the UV using the WN sequence. A previously unpublished spectrum of WR 48 (WC6 + O9.5 I), obtained with HUT during the 1990 December Astro-1 mission, allows for a comparison of the WN sequence with one WC spectrum.
