Is the wind of the Oe star HD 155806 magnetically confined?
V. Petit, A. W. Fullerton, S. Bagnulo +1
Oe stars are a subset of the O-type stars that exhibit emission lines from a circumstellar disk. The recent detection of magnetic fields in some O-type stars suggests a possible ex…
Structure and clumping in the fast wind of NGC6543
R. K. Prinja, S. E. Hodges, D. L. Massa +2
Far-UV spectroscopy from the FUSE satellite is analysed to uniquely probe spatial structure and clumping in the fast wind of the central star of the H-rich planetary nebula NGC6543…
CalFUSE v3: A Data-Reduction Pipeline for the Far Ultraviolet Spectroscopic Explorer
W. V. Dixon, D. J. Sahnow, P. E. Barrett +13
Since its launch in 1999, the Far Ultraviolet Spectroscopic Explorer (FUSE) has made over 4600 observations of some 2500 individual targets. The data are reduced by the Principal I…
Cepheid Masses: FUSE Observations of S Mus
Nancy Remage Evans, Derck Massa, Alexander Fullerton +2
S Mus is the Cepheid with the hottest known companion. The large ultraviolet flux means that it is the only Cepheid companion for which the velocity amplitude could be measured wit…
FUSE observations of HD 5980: The wind structure of the eruptor
Gloria Koenigsberger, Alexander W. Fullerton, Derck Massa +1
HD 5980 is a unique system containing one massive star (star A) that is apparently entering the luminous blue variable phase, and an eclipsing companion (star B) that may have alre…
Origin of Structures in Wolf-Rayet Winds: FUSE Observations of WR 135
S. V. Marchenko, A. F. J. Moffat, N. St-Louis +1
We report the detection with FUSE of strong, highly blue-shifted absorption features appearing in the absorption troughs of practically all major P Cygni profiles in the presumably…
The magnetic field and confined wind of the O star ~Orionis~C
G. A. Wade, A. W. Fullerton, J. -F. Donati +3
In this paper we confirm the presence of a globally-ordered, kG-strength magnetic field in the photosphere of the young O star ~Orionis~C, and examine the properties of its op…
A Revised Geometry for the Magnetic Wind of theta^1 Orionis C
Myron A. Smith, Alex W. Fullerton
Theta^1 Ori is thought to be a hot analog of Bp variables because its optical and UV line and X-ray continuum fluxes modulate regularly over the magnetic/rotational period. A flatt…
FUSE Observations of Variability in Hot-Star Winds
A. W. Fullerton, D. L. Massa, R. K. Prinja +3
New constraints on the large-scale wind structures responsible for discrete absorption components are obtained from far-ultraviolet time-series observations of O supergiants in the…
A close binary nucleus in the most oxygen-poor planetary nebula PN G 135.9+55.9
G. H. Tovmassian, R. Napiwotzki, M. G. Richer +3
We report FUSE and new deep optical spectroscopic observations of PN G 135.9+55.9, the most oxygen-poor planetary nebula located in the Galactic halo. These observations allow us t…
Constraints on the Ionization Balance of Hot-Star Winds from FUSE Observations of O Stars in the Large Magellanic Cloud
D. Massa, A. W. Fullerton, G. Sonneborn +1
We use a Sobolev with Exact Integration model to analyze the winds lines of 25 LMC O stars. The data include FUSE profiles of C III, N III, S IV, P V, S VI, and O VI and IUE or HST…
An Atlas of Galactic Spectra Observed with the Far Ultraviolet Spectroscopic Explorer
A. Pellerin, A. W. Fullerton, C. Robert +6
An atlas of far-ultraviolet spectra of 45 Galactic OB stars observed with the Far Ultraviolet Spectroscopic Explorer is presented. The atlas covers the wavelength region between 91…
Revised Stellar Temperatures for Magellanic Cloud O Supergiants from FUSE and VLT-UVES Spectroscopy
P. A. Crowther, D. J. Hillier, C. J. Evans +3
We have undertaken quantitative analysis of four LMC and SMC O4--9.7 extreme supergiants using far-ultraviolet FUSE, ultraviolet IUE/HSTand optical VLT UVES spectroscopy. Extended,…
FUSE 900-1200A Spectroscopy of AM Her
J. B. Hutchings, A. W. Fullerton, A. P. Cowley +1
Spectra of the magnetic white dwarf binary AM Her were obtained with the Far Ultraviolet Spectroscopic Explorer (FUSE) during three consecutive spacecraft orbits. These observation…
