Abstract

The Far Ultraviolet Spectroscopic Explorer has provided an extensive sample of spectra of OB stars in the Magellanic Clouds in the 900-1200 Å range. The shorter wavelengths are more accesible in the Clouds than in the Galaxy, because of the lower interstellar extinction and absorption. Many additional objects have been observed since the initial compilation by Walborn et al. (2002, ApJS, 141, 443). These new data have been reduced and organized into spectral-type sequences, including additional very early O stars, some with CNO anomalies (see Walborn 2009, RevMexAA (SC), 35, 170); late-O supergiants; and late WN stars.
