Long-term eclipse timing of white dwarf binaries: an observational hint of a magnetic mechanism at work
M. C. P. Bours, T. R. Marsh, S. G. Parsons +18
We present a long-term programme for timing the eclipses of white dwarfs in close binaries to measure apparent and/or real variations in their orbital periods. Our programme includ…
The post-outburst pulsations of the accreting white dwarf in the cataclysmic variable GW Librae
P. Chote, D. J. Sullivan
We present new time-series photometry of the accreting pulsating white dwarf system GW Librae obtained in 2012 and 2013 at the University of Canterbury Mt John Observatory in New Z…
Insights into internal effects of common-envelope evolution using the extended Kepler mission
J. J. Hermes, B. T. Gaensicke, A. Bischoff-Kim +14
We present an analysis of the binary and physical parameters of a unique pulsating white dwarf with a main-sequence companion, SDSS J1136+0409, observed for more than 77 d during t…
Simulating the photometric study of pulsating white dwarf stars in the physics laboratory
Paul Chote, Denis J. Sullivan
We have designed a realistic simulation of astronomical observing using a relatively low-cost commercial CCD camera and a microcontroller-based circuit that drives LEDs inside a li…
