An Atlas of Galactic OB Spectra Observed with the Far Ultraviolet Spectroscopic Explorer

An atlas of far-ultraviolet spectra of 45 Galactic OB stars observed with the Far Ultraviolet Spectroscopic Explorer is presented. The atlas covers the wavelength region between 912 and 1185 Å with an effective spectral resolution of 0.12 Å. Systematic trends in the morphology and strength of stellar features are discussed. Particular attention is drawn to the variations of the C III λ1176, S IV λλ1063, 1073, and P V λλ1118, 1128 line profiles as a function of temperature and luminosity class; and the lack of a luminosity dependence associated with O VI λλ1032, 1038. Numerous interstellar lines are also identified.
