Discovery of ZZ Cetis in detached white dwarf plus main-sequence binaries
S. Pyrzas, B. T. Gaensicke, J. J. Hermes +12
We present the first results of a dedicated search for pulsating white dwarfs (WDs) in detached white dwarf plus main-sequence binaries. Candidate systems were selected from a cata…
Testing the planetary models of HU Aquarii
M. Bours, T. Marsh, E. Breedt +6
We present new eclipse observations of the polar (i.e. semi-detached magnetic white dwarf + M-dwarf binary) HU Aqr, and mid-egress times for each eclipse, which continue to be obse…
The substellar companion in the eclipsing white dwarf binary SDSS J141126.20+200911.1
S. P. Littlefair, S. L. Casewell, S. G. Parsons +14
We present high time resolution SDSS- and SDSS- light curves of the primary eclipse in SDSS J141126.20+200911.1, together with time-resolved X-Shooter spectroscopy and near…
Variable Emission from a Gaseous Disc around a Metal-Polluted White Dwarf
David J Wilson, Boris Gaensicke, Detlev Koester +4
We present the discovery of strongly variable emission lines from a gaseous disc around the DA white dwarf SDSS J1617+1620, a star previously found to have an infrared excess indic…
Heavy metals in a light white dwarf: Abundances of the metal-rich, extremely low-mass GALEX J1717+6757
J. J. Hermes, B. T. Gaensicke, D. Koester +9
Using the Hubble Space Telescope, we detail the first abundance analysis enabled by far-ultraviolet spectroscopy of a low-mass (~0.19 Msun) white dwarf (WD), GALEX J1717+6757, whic…
Swift monitoring of NGC 5548: X-ray reprocessing and short term UV/optical variability
I. M. McHardy, D. T. Cameron, T. Dwelly +7
Lags measured from correlated X-ray/UV/optical monitoring of AGN allow us to determine whether UV/optical variability is driven by reprocessing of X-rays or X-ray variability is dr…
