Excitation mechanisms in newly discovered H2-bearing Damped Lyman-alpha clouds: systems with low molecular fractions
P. Noterdaeme, C. Ledoux, P. Petitjean +3
We probe the physical conditions in high-redshift damped Ly-alpha systems using the observed molecular fraction and the rotational excitation of molecular hydrogen. We report two n…
Physical conditions in the neutral interstellar medium at z=2.43 toward Q2348-011
P. Noterdaeme, P. Petitjean, R. Srianand +2
We obtained a high-resolution VLT-UVES spectrum of the quasar Q2348-011 over a wavelength range that covers most of the prominent metal and molecular absorption lines from the log…
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) =…
A far UV study of interstellar gas towards HD34078: high excitation H2 and small scale structure - Based on observations performed by the FUSE mission and at the CFHT telescope
P. Boisse, F. Le Petit, E. Rollinde +5
To investigate the presence of small scale structure in the spatial distribution of H2 molecules we have undertaken repeated FUSE UV observations of the runaway O9.5V star, HD34078…
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.…
FUSE observations of H2 around the Herbig AeBe stars HD 100546 and HD 163296
A. Lecavelier des Etangs, M. Deleuil, A. Vidal-Madjar +6
We present the analysis of FUSE observations of two Herbig AeBe stars known to harbor young circumstellar disks: HD 100546 and HD 163296. In both cases we detect absorption lines f…
