Million Degree Plasmas in Extreme Ultraviolet (EUV) Astrophysics (2009)
Kowalski, Michael P., Barstow, Martin, Bruhweiler, Frederick, Cruddace, Raymond, Dupree, Andrea, Holberg, Jay, ...
Million degree plasmas are ubiquitous in the Universe, and examples include the atmospheres of white dwarfs; accretion phenomena in young stars, cataclysmic variables and active galactic nuclei; the...
HOT WHITE DWARFS IN NON-INTERACTING BINARIES FROM THE ROSAT EUV SURVEY (2007)
Matthew Burleigh, Martin Barstow
More than 120 hot white dwarfs have been identified in the extreme ultraviolet (EUV) survey of the ROSAT Wide Field Camera (WFC, Pye et al., 1995). The majority of these are isolated stars, but, in...
The pulsation modes of the pre-white dwarf PG 1159-035 (2007)
Costa, J. E. S., Kepler, S. O., Winget, D. E., O'Brien, M. S., Kawaler, S. D., Costa, A. F. M., ...
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 1159-035 photometric data...
Photospheric phosphorus in the FUSE spectra of GD71 and two similar DA white dwarfs (2005)
Dobbie, Paul, Barstow, Martin, Hubeny, Ivan, Holberg, Jay, Burleigh, Matt, Forbes, Anne
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 of the...
A near-IR spectrum of the DO white dwarf RE J0503-285 (2005)
Dobbie, Paul, Burleigh, Matt, Levan, Andrew, Barstow, Martin, Napiwotzki, Ralf, Hubeny, Ivan, ...
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, late-type...
Resolving Sirius-like binaries with the Hubble Space Telescope (2000)
Burleigh, Matt, Barstow, Martin, Bond, Howard E., Holberg, Jay
We have imaged seventeen recently discovered Sirius-like binary systems with HST/WFPC2 and resolved the white dwarf secondary in eight cases. Most of the implied orbital periods are of order several...
Spectroscopic confirmation of a white dwarf companion to the B star 16 Dra (2000)
Burleigh, Matt, Barstow, Martin
Using an Extreme Ultraviolet Explorer (EUVE) spectrum, we confirm the identification of a white dwarf companion to the B9.5V star 16 Dra (HD150100), and constrain its surface temperature to lie...
HR2875: Spectroscopic discovery of the first B star + white dwarf binary (1998)
Burleigh, Matt, Barstow, Martin
We report the discovery, in an Extreme Ultraviolet Explorer (EUVE) short wavelength spectrum, of an unresolved hot white dwarf companion to the 5th-magnitude B5Vp star HR2875. This is the first time...
A search for hidden white dwarfs in the ROSAT EUV survey (1997)
Burleigh, Matt, Barstow, Martin, Fleming, Tom
The ROSAT WFC survey has provided us with evidence for the existence of a previously unidentified sample of hot white dwarfs (WD) in non-interacting binary systems, through the detection of EUV and...
