Hunting For Eclipses: High Speed Observations of Cataclysmic Variables
Liam K Hardy, Martin J McAllister, Vik S Dhillon +12
We present new time-resolved photometry of 74 cataclysmic variables (CVs), 47 of which are eclipsing. 13 of these eclipsing systems are newly discovered. For all 47 eclipsing syste…
Using Gaussian processes to model light curves in the presence of flickering: the eclipsing cataclysmic variable ASASSN-14ag
M. J. McAllister, S. P. Littlefair, V. S. Dhillon +10
The majority of cataclysmic variable (CV) stars contain a stochastic noise component in their light curves, commonly referred to as flickering. This can significantly affect the mo…
A double white dwarf with a paradoxical origin?
M. C. P. Bours, T. R. Marsh, B. T. Gaensicke +14
We present Hubble Space Telescope UV spectra of the 4.6 h period double white dwarf SDSS J125733.63+542850.5. Combined with Sloan Digital Sky Survey optical data, these reveal that…
HST+COS spectra of the double white dwarf CSS 41177 place the secondary inside the pulsational instability strip
Madelon Bours, Thomas Marsh, Boris Gaensicke +1
We present Hubble Space Telescope + Cosmic Origins Spectrograph (HST+COS) data of the eclipsing double white dwarf binary CSS 41177. Due to the temperature difference between the t…
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…
