Velocity Dispersion of Excited H2
S. Lacour, V. Ziskin, G. Hebrard +4
We present a study of the high rotational bands (J > 2) of H2 toward 4 early type galactic stars: HD 73882, HD 192639, HD 206267, and HD 207538. In each case, the velocity dispersi…
Deuterated molecular hydrogen in the Galactic ISM. New observations along seven translucent sightlines
S. Lacour, M. K. Andre, P. Sonnentrucker +6
We present column density measurements of the HD molecule in the interstellar gas toward 17 Galactic stars. The values for the seven most heavily reddened sightlines, with E(B-V) =…
Tiny-Scale Molecular Structures in the Magellanic Clouds (Part 1)
Kuassivi-Andre, F. Lepetit, P. Sonnentrucker +6
We report on the {\small FUSE} detections of the HD and CO molecules {\bf on the lines of sight towards three Large Magellanic stars}: Sk 67D05, Sk 68D135, and Sk 69D246.…
Oxygen Gas Phase Abundance Revisited
M. K. André, C. M. Oliveira, J. C. Howk +7
We present new measurements of the interstellar gas-phase oxygen abundance along the sight lines towards 19 early-type galactic stars at an average distance of 2.6 kpc. We derive O…
Deuterium abundance toward G191-B2B: Results from the Far Ultraviolet Spectroscopic Explorer (FUSE) Mission
M. Lemoine, A. Vidal-Madjar, G. Hebrard +19
High-resolution spectra of the hot white dwarf G191-B2B, covering the wavelength region 905-1187A, were obtained with the Far Ultraviolet Spectroscopic Explorer (FUSE). This data w…
