What Is the Total Deuterium Abundance in the Local Galactic Disk
Jeffrey L. Linsky,Bruce T. Draine,H. W. Moos,Edward B. Jenkins,Brian E. Wood,Cristina Oliveira,William P. Blair,Scott D. Friedman,Cecile Gry,David C. Knauth,Jeffrey W. Kruk,Sylvestre Lacour,Nicolas Lehner,Seth Redfield,J. Michael Shull,George Sonneborn,Gerard M. Williger +16 more
TL;DR: In this paper, the authors present a variable deuterium depletion model that naturally explains the constant measured values of D/H inside the Local Bubble, the wide range of gas-phase D/h ratios observed in the intermediate regime [log N(H ) = 19.2-20.7], and the low gas phase D/C ratios observed at larger hydrogen column densities.

TL;DR: In this article, the authors present a variable deuterium depletion model that naturally explains the constant measured values of D/H inside the Local Bubble, the wide range of gas-phase D/h ratios observed in the intermediate regime (log N(H I} = 19.2-20.7), and the low gas phase D/hr ratios observed at larger hydrogen column densities.

Oxygen Gas-Phase Abundance Revisited
M. K. André,M. K. André,Cristina Oliveira,J. C. Howk,Roger Ferlet,Jean-Michel Desert,Guillaume Hébrard,Sylvestre Lacour,A. Lecavelier des Etangs,Alfred Vidal-Madjar,H. W. Moos +10 more
TL;DR: In this paper, the authors presented new measurements of the interstellar gas-phase oxygen abundance along the sight lines toward 19 early-type Galactic stars at an average distance of 2.6 kpc.
Journal ArticleDOI
Interstellar Deuterium, Nitrogen, and Oxygen Abundances Toward GD 246, WD 2331$-$475, HZ 21, and Lan 23: Results from the FUSE Mission
Cristina Oliveira,Guillaume Hébrard,J. Christopher Howk,Jeffrey W. Kruk,Pierre Chayer,H. Warren Moos +5 more
TL;DR: In this paper, the high-resolution spectra of four hot white dwarfs were obtained with the Far Ultraviolet Spectroscopic Explorer (FUSE) in the wavelength range 905-1187 A. The column densities of H I, C II*, S II, and Si II were measured using archival STIS echellemode observations.
