Far Ultraviolet Spectroscopic Explorer Observations of the Dwarf Nova Sw Ursae Majoris during Quiescence

We present spectroscopic observations of the short-period cataclysmic variable SW UMa obtained by the Far Ultraviolet Spectroscopic Explorer (FUSE) satellite while the system was in quiescence. The data include the resonance lines of O vi at 1031.91 and 1037.61 8. These lines are present in emission, and they exhibit both narrow ( 150 km s ) and broad ( 2000 km s ) components. The narrow O vi e...

Deuterium toward the White Dwarf Wd0621−376: Results from the Far Ultraviolet Spectroscopic Explorer (fuse) Mission

Far Ultraviolet Spectroscopic Explorer observations are presented for WD0621−376, a DA white dwarf star in the local interstellar medium (LISM) at a distance of about 78 pc. The data have a signal-tonoise ratio of ∼20–40 per 20 km s resolution element and cover the wavelength range 905–1187 Å. LISM absorption is detected in the lines of D I, C II, C II*, C III, N I, N II, N III, O I, Ar I, and ...

Far Ultraviolet Spectroscopic Explorer Measurements of Interstellar Fluorine

The source of fluorine is not well understood, although core-collapse supernovae, Wolf-Rayet stars, and asymptotic giant branch stars have been suggested. A search for evidence of the -process during Type II supernovae is presented. Absorption from interstellar F i is seen in spectra of HD 208440 and HD 209339A acquired with the Far Ultraviolet Spectroscopic Explorer. In order to extract the co...

dayglow emission observed by the Far Ultraviolet Spectroscopic Explorer

[1] Terrestrial thermospheric dayglow emission from the coupled and overlapping c0 4 Su (0) and b0 Su (1) levels of molecular nitrogen, observed by the Far Ultraviolet Spectroscopic Explorer, is analyzed with the aid of a coupled channels quantum mechanical model of N2 spectroscopy and predissociation dynamics. Model emission spectra for the mixed c0 4 Su (0) b0 Su(1) X Sg(vi = 2, 6–9) transiti...

Far Ultraviolet Spectroscopic Explorer Survey of the Local Interstellar Medium within 200 Parsec

We present Far Ultraviolet Spectroscopic Explorer observations of the interstellar gas toward 30 white dwarf and 1 subdwarf (SdO) stars. These sightlines probe the Local Bubble (LB) and the local interstellar medium (LISM) near the LB. We systematically measure the column densities for the following species: C II, C II*, C III, N I, N II, O I, Ar I, Si II, P II, Fe II, Fe III, and H2. Our surve...
