Spectral analysis of the sdO standard star Feige 34
M. Latour, P. Chayer, E. M. Green +1
We present our current work on the spectral analysis of the hot sdO star Feige 34. We combine high S/N optical spectra and fully-blanketed non-LTE model atmospheres to derive its f…
Effect of Radiative Levitation on Calculations of Accretion Rates in White Dwarfs
P. Chayer, J. Dupuis
Elements heavier than hydrogen or helium that are present in the atmospheres of white dwarfs with effective temperatures lower than 25,000 K, are believed to be the result of accre…
A NLTE model atmosphere analysis of the pulsating sdO star SDSS J1600+0748
M. Latour, G. Fontaine, P. Brassard +2
We started a program to construct several grids of suitable model atmospheres and synthetic spectra for hot subdwarf O stars computed, for comparative purposes, in LTE, NLTE, with…
Modeling of the Lyman gamma satellites in FUSE spectra of DA white dwarfs
G. Hébrard, N. F. Allard, J. F. Kielkopf +4
We present new theoretical calculations of the line profile of Lyman gamma that include transitions in which a photon is absorbed by a neutral hydrogen atom while it interacts with…
Abundances of Deuterium, Oxygen, and Nitrogen in the Local Interstellar Medium: Overview of First Results from the Far Ultraviolet Spectroscopic Explorer Mission
H. W. Moos, K. R. Sembach, A. Vidal-Madjar +33
Observations obtained with the Far Ultraviolet Spectroscopic Explorer (FUSE) have been used to determine the column densities of D I, O I, and N I along seven sight lines that prob…
