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… Expand

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. TheseExpand
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)Expand
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 ofExpand
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)Expand
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 inExpand
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 theExpand
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?Expand
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 deuteriumExpand
(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 nucleosynthesisExpand
On the deuterium abundance and the importance of stellar mass loss in the interstellar and intergalactic medium
We quantify the gas-phase abundance of deuterium and fractional contribution of stellar mass loss to the gas in cosmological zoom-in simulations from the Feedback In Realistic Environments project.Expand


Deuterium Abundance in the Interstellar Gas of the Galactic Anticenter from the 327 MHz Line
The deuterium abundance in the primordial gas formed during the big bang is dependent on the baryon-to-photon ratio during nucleosynthesis. We report a measurement of the deuterium-to-hydrogen (D/H)Expand
Evidence of Correlated Titanium and Deuterium Depletion in the Galactic Interstellar Medium
Current measurements indicate that the deuterium abundance in diffuse interstellar gas varies spatially by a factor of ~4 among sight lines extending beyond the Local Bubble. One plausibleExpand
