Analyses of spectra obtained with the Far Ultraviolet Spectroscopic Explorer (FUSE) satellite, together with spectra from the Copernicus and interstellar medium absorption profile spectrograph (IMAPS) instruments, reveal an unexplained, very wide range in the observed deuterium/hydrogen (D/H) ratios for interstellar gas in the Galactic disk beyond the Local Bubble. We argue that spatial variations in the depletion of deuterium onto dust grains can explain these local variations in the observed…

Abstract Analyses of FUSE spacecraft spectra have provided measurements of D/H in the gas phase of the interstellar medium for many lines of sight extending to several kpc from the Sun. These

The Galactic deuterium abundance and dust depletion: insights from an expanded Ti/H sample

The primordial abundance of deuterium (D/H) yields a measure of the density of baryons in the Universe and is an important complement to determinations from cosmic microwave background (CMB)

FUSE deuterium observations: a strong case for galactic infall

Measurements of deuterium in the local interstellar medium have revealed large variations in D/H along different lines of sight. Moreover, recent far-ultraviolet spectroscopic explorer (FUSE)

Gas-phase Deuterium Abundances, Near and Far

Deuterium abundances in gaseous media reveal information on the baryon density of the universe Ω b and the processing of chemical elements by stars in galaxies. By observing D in its atomic form in

D/H and Nearby Interstellar Cloud Structures

Abstract Analysis of UV spectra obtained with the HST, FUSE and other satellites provides a new understanding of the deuterium abundance in the local region of the galactic disk. The wide range of

The deuterium abundance in the local interstellar medium

As the Galaxy evolves, the abundance of deuterium in the interstellar medium (ISM) decreases from its primordial value: deuterium is ‘astrated’. The deuterium astration factor f D, the ratio of the

On the Deuterium-to-hydrogen Ratio of the Interstellar Medium

Observational studies show that the global deuterium-to-hydrogen ratio in the local interstellar medium (ISM) is about 90% of the primordial ratio predicted by Big Bang nucleosynthesis. The high

The Abundance of Deuterium in the Warm Neutral Medium of the Lower Galactic Halo

We use high-resolution ultraviolet spectra to obtain Milky Way interstellar column densities of H I, D I, O I, S II, Fe II, and P II toward the QSO HE 0226-4110 in the Galactic direction l = 253.4°

(Un)true deuterium abundance in the Galactic disk

Abstract Deuterium has a special place in cosmology, nuclear astrophysics, and galactic chemical evolution, because of its unique property that it is only created in the big bang nucleosynthesis

New metallicity independent constraints of galactic infall from deuterium observations

Local deuterium observations have shown large variations over different lines of sight. However, it has been recently proposed that such variations can be explained by strong depletion of deuterium
