Scientific paper

We propose to use the IUE to obtain low-dispersion far ultraviolet continuum flux distributions for a group of rapidly rotating, lightly reddened B and Be stars in the ScoCen association. The ultraviolet continuous energy distribution of a rapidly rotating early-type star is particularly sensitive to both the equatorial rotation velocity and the angle of inclination of the stellar rotation axis to the observer's line of sight. This data set will be used to study any systematic differences between rotating B and Be stars at similar vsini and spectral type, as well as indicating the frequency and nature of any circumstellar extinction. The data will also be compared against model flux distributions for rapidly rotating B stars., Since all of the program stars are bright, only US shift 2 time will be required.
