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…
ULTRASPEC: a high-speed imaging photometer on the 2.4-m Thai National Telescope
V. S. Dhillon, T. R. Marsh, D. C. Atkinson +18
ULTRASPEC is a high-speed imaging photometer mounted permanently at one of the Nasmyth focii of the 2.4-m Thai National Telescope (TNT) on Doi Inthanon, Thailand's highest mountain…
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…
A parameter study of the eclipsing CV in the Kepler field, KIS J192748.53+444724.5
S. P. Littlefair, V. S. Dhillon, B. T Gaensicke +3
We present high-speed, three-colour photometry of the eclipsing dwarf nova KIS J192748.53+444724.5 which is located in the Kepler field. Our data reveal sharp features correspondin…
Precise parameters for both white dwarfs in the eclipsing binary CSS 41177
M. C. P. Bours, T. R. Marsh, S. G. Parsons +6
We present ULTRACAM photometry and X-Shooter spectroscopy of the eclipsing double white dwarf binary CSS 41177, the only such system that is also a double-lined spectroscopic binar…
