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

摘要

An atlas of far-ultraviolet spectra of 45 Galactic OB stars observed with theFar Ultraviolet Spectroscopic Explorer is presented. The atlas covers thewavelength region between 912 and 1185A with an effective spectral resolutionof 0.12A. Systematic trends in the morphology and strength of stellar featuresare discussed. Particular attention is drawn to the variations of theCIII$lambda$1176, SIV$lambdalambda$1063, 1073, and PV$lambdalambda$1118,1128 line profiles as a function of temperature and luminosity class; and thelack of a luminosity dependence associated with OVI$lambdalambda$1032, 1038.Numerous interstellar lines are also identified.
