Evidence for deuterium astration in the planetary nebula Sh2-216?
Cristina M Oliveira, Pierre Chayer, H. Warren Moos +2
We present FUSE observations of the line of sight to WD0439+466 (LS V +46 21), the central star of the old planetary nebula Sh2-216. The FUSE data shows absorption by many interste…
The UV spectrum of HS1700+6416 II. FUSE observations of the HeII Lyman alpha forest
C. Fechner, D. Reimers, G. A. Kriss +11
We present the far-UV spectrum of the quasar HS1700+6416 taken with FUSE. This QSO provides the second line of sight with the HeII absorption resolved into a Ly alpha forest struct…
Variations in D/H and D/O from New FUSE Observations
C. M. Oliveira, H. Warren Moos, Pierre Chayer +1
We use data obtained with the Far Ultraviolet Spectroscopic Explorer (FUSE) to determine the interstellar abundances of DI, NI, OI, FeII, and H2 along the sigh tlines to WD1034+001…
FUSE determination of a low deuterium abundance along an extended sight line in the Galactic disk
G. Hebrard, T. M. Tripp, P. Chayer +5
We present a study of the deuterium abundance along the extended sight line (2.7kpc) toward HD 90087 with FUSE. Both in terms of distance and column densities, HD 90087 has the lon…
O/H in the Local Bubble
Cristina Oliveira, Jean Dupuis, Pierre Chayer +1
We present new measurements of the oxygen gas-phase abundance along four sightlines probing gas inside the Local Bubble, using data obtained with the Far Ultraviolet Spectroscopic…
The D/H Ratio in the Interstellar Medium toward the White Dwarf PG0038+199
G. M. Williger, C. Oliveira, G. Hebrard +3
We determine the D/H ratio in the interstellar medium toward the DO white dwarf PG0038+199 using spectra from the Far Ultraviolet Spectroscopic Explorer (FUSE), with ground-based s…
