FUSE and HST/STIS far-ultraviolet observations of AM Herculis in an extended low state
B. T. Gaensicke, K. S. Long, M. A. Barstow +1
We have obtained FUSE and HST/STIS time-resolved spectroscopy of the polar AM Herculis during a deep low state. The spectra are entirely dominated by the emission of the white dwar…
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…
Photospheric phosphorus in the FUSE spectra of GD71 and two similar DA white dwarfs
Paul Dobbie, Martin Barstow, Ivan Hubeny +3
We report the detection, from FUSE data, of phosphorus in the atmospheres of GD71 and two similar DA white dwarfs. This is the first detection of a trace metal in the photosphere o…
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…
Hubble Space Telescope Spectroscopy of the Balmer lines in Sirius B
M. A. Barstow, Howard E. Bond, J. B. Holberg +3
Sirius B is the nearest and brightest of all white dwarfs, but it is very difficult to observe at visible wavelengths due to the overwhelming scattered light contribution from Siri…
A near-IR spectrum of the DO white dwarf RE J0503-285
Paul Dobbie, Matt Burleigh, Andrew Levan +4
We present a near-IR spectroscopic analysis of the intriguing DO white dwarf RE J0503-285. The IR spectrum fails to reveal evidence of the presence of a spatially unresolved, cool,…
