    GHRS observations of the LISM (1996)
    Springer
    Space science reviews 78 (1996), S. 157-164

    Notes: Abstract The GHRS has obtained high-resolution spectra of interstellar gas toward 19 nearby stars. These excellent data show that the Sun is located inside the Local Interstellar Cloud (LIC) with other warm clouds nearby. I will summarize the physical properties of these clouds and the three-dimensional structure of this warm interstellar gas. There is now clear evidence that the Sun and other late-type stars are surrounded by hydrogen walls in the upwind direction. The D/H ratio probably has a constant value in the LIC, (1.6 ± 0.2) × 10−5, consistent with the measured values for all LIC lines of sight.

    Deuterium Abundance in the Local ISM and Possible Spatial Variations (1998)
    Springer
    Space science reviews 84 (1998), S. 285-296 
    Details
    ISSN: 1572-9672
    Keywords: LISM ; interstellar medium ; deuterium
    Source: Springer Online Journal Archives 1860-2000
    Topics: Physics
    Notes: Abstract Excellent HST/GHRS spectra of interstellar hydrogen and deuterium Lyman-α absorption toward nearby stars allow us to identify systematic errors that have plagued earlier work and to measure accurate values of the D/H ratio in local interstellar gas. Analysis of 12 sightlines through the Local Interstellar Cloud leads to a mean value of D/H = (1.50 ± 0.10) × 10-5 with all data points lying within ± 1σ of the mean. Whether or not the D/H ratio has different values elsewhere in the Galaxy and beyond is a very important open question that will be one of the major objectives of the Far Ultraviolet Spectroscopic Explorer (FUSE) mission.
