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…
White paper: Gaia and the end states of stellar evolution
M. A Barstow, S. L. Casewell, S. Catalan +18
This is the product of a Gaia GREAT workshop on "Gaia and the end states of stellar evolution" held at the University of Leicester in April 2011.
The evolution of the self-lensing binary KOI-3278: evidence of extra energy sources during CE evolution
M. Zorotovic, M. R. Schreiber, S. G. Parsons
Post-common-envelope binaries (PCEBs) have been frequently used to observationally constrain models of close-compact-binary evolution, in particular common-envelope (CE) evolution.…
