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…
GRB 060206 and the quandary of achromatic breaks in afterglow light curves
P. A. Curran, A. J. van der Horst, R. A. M. J. Wijers +20
Gamma-ray burst afterglow observations in the Swift era have a perceived lack of achromatic jet breaks compared to the BeppoSAX era. We present our multi-wavelength analysis of GRB…
Heavy element abundances in DA white dwarfs
M. A. Barstow, M. R. Burleigh, N. P. Bannister +4
We present a series of systematic abundance measurements for a group of hot DA white dwarfs in the temperature range 20,000-75,000K, based on far-UV spectroscopy with STIS on HST,…
FUSE Observations of the hottest DA white dwarfs
M. A. Barstow, M. R. Burleigh, N. P. Bannister +2
We report early FUSE observations of the very hot DA white dwarfs PG1342+444 and REJ0558-371. Detection of photospheric absorption lines allows us to estimate the abundances of C,…
Resolving Sirius-like binaries with the Hubble Space Telescope
Matt Burleigh, Martin Barstow, Howard E. Bond +1
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 ar…
Spectroscopic confirmation of a white dwarf companion to the B star 16 Dra
Matt Burleigh, Martin Barstow
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 tempe…
