The Far Ultraviolet Spectroscopic Explorer Survey of O VI Absorption in and near the Galaxy

Kruk, J. W.; Savage, B. D.; Wakker, B. P. +18 more

We present Far Ultraviolet Spectroscopic Explorer (FUSE) observations of the O VI λλ1031.926, 1037.617 absorption lines associated with gas in and near the Milky Way, as detected in the spectra of a sample of 100 extragalactic targets and two distant halo stars. We combine data from several FUSE Science Team programs with guest observer data that …

The Structure of Stellar Coronae in Active Binary Systems

Sanz-Forcada, J.; Dupree, A. K.; Brickhouse, N. S.

A survey of 28 stars (22 active binary systems, plus six single stars or wide binaries for comparison) using extreme ultraviolet spectra has been conducted to establish the structure of stellar coronae in active binary systems from the emission measure distribution (EMD), electron densities, and scale sizes. Observations obtained by the Extreme Ul…

An IUE Atlas of Pre-Main-Sequence Stars. III. Co-added Final Archive Spectra from the Long-Wavelength Cameras

Valenti, Jeff A.; Johns-Krull, Christopher M.; Fallon, Adam A.

We identified 137 T Tauri stars (TTS) and 97 Herbig Ae/Be (HAEBE) stars observed by IUE in the wavelength interval 1900-3200 Å. Each low-resolution (R~6 Å) spectrum was visually inspected for source contamination and data quality, and then all usable spectra were combined to form a single time averaged spectrum for each star. For sources with mult…

An Archive of IUE Low-Dispersion Spectra of the White Dwarf Stars

Barstow, M. A.; Holberg, J. B.; Burleigh, M. R.

We have produced an archive of the ultraviolet low-dispersion spectra for the full set of white dwarf stars observed with the International Ultraviolet Explorer (IUE) satellite over the course of its 18 yr mission. This archive contains the spectra of 322 individual degenerate stars which have been processed to optimize the signal-to-noise for eac…
