The pulsation modes of the pre-white dwarf PG 1159-035
J. E. S. Costa, S. O. Kepler, D. E. Winget +74
PG 1159-035, a pre-white dwarf with T_eff=140,000 K, is the prototype of both two classes: the PG1159 spectroscopic class and the DOV pulsating class. Previous studies of PG 1159-0…
A search for binarity using FUSE observations of DAO white dwarfs
S. A. Good, M. A. Barstow, M. R. Burleigh +2
We report on a search for evidence of binarity in Far-Ultraviolet Spectroscopic Explorer (FUSE) observations of DAO white dwarfs. Spectra recorded by FUSE are built up from a numbe…
Heavy element abundances in DAO white dwarfs measured from FUSE data
S. A. Good, M. A. Barstow, M. R. Burleigh +3
We present heavy element abundance measurements for 16 DAO white dwarfs, determined from Far-Ultraviolet Spectroscopic Explorer {FUSE} spectra. Evidence of absorption by heavy elem…
Rotational period of WD1953-011 - a magnetic white dwarf with a star spot
C. S. Brinkworth, T. R. Marsh, L. Morales-Rueda +3
WD1953-011 is an isolated, cool (7920 +/- 200K, Bergeron, Legget & Ruiz, 2001) magnetic white dwarf (MWD) with a low average field strength (~70kG, Maxted et al. 2000) and a higher…
Observations of the pulsating subdwarf B star Feige 48: Constraints on evolution and companions
M. D. Reed, S. D. Kawaler
Since pulsating subdwarf B (sdBV or EC14026) stars were first discovered (Kilkenny et al, 1997), observational efforts have tried to realize their potential for constraining the in…
A comparison of DA white dwarf temperatures and gravities from FUSE Lyman line and ground-based Balmer line observations
M. A. Barstow, S. A. Good, M. R. Burleigh +3
Observation of the strengths and profiles of the hydrogen Balmer absorption series is an established technique for determining the effective temperature and surface gravity of hot…
