FUSE and HST STIS Observations of Hot and Cold Gas in the AB Aurigae System
A. Roberge, A. Lecavelier des Etangs, C. A. Grady +9
We present the first observations of a Herbig Ae star with a circumstellar disk by the Far Ultraviolet Spectroscopic Explorer (FUSE), as well as a simultaneous observation of the s…
AB Dor in '94: I. HST/GHRS Observations of the Quiescent Chromosphere of an Active Star
J. C. Brandt, S. R. Heap, F. M. Walter +15
We analyze HST/GHRS spectra of AB Doradus, the prototypical ultra-rapidly rotating K dwarf. We observed chromospheric (Mg II) and transition region (C II, Si IV, C IV, and N V) lin…
Intrinsic Absorption Lines in Seyfert 1 Galaxies. I. Ultraviolet Spectra from the Hubble Space Telescope
D. Michael Crenshaw, Steven B. Kraemer, Albert Boggess +3
We present a study of the intrinsic absorption lines in the ultraviolet spectra of Seyfert 1 galaxies. We find that the fraction of Seyfert 1 galaxies that show absorption associat…
Spatially Resolved STIS Spectroscopy of SN 1987A: Evidence for Shock Interaction with Circumstellar Gas
G. Sonneborn, C. S. J. Pun, R. A. Kimble +15
Visual and ultraviolet spatially resolved (~ 0."1) spectra of SN 1987A obtained on days 3715 and 3743 with the Space Telescope Imaging Spectrograph on the Hubble Space Telescope sh…
