Roche tomography of the secondary stars in CVs
C. A. Watson, V. S. Dhillon
The secondary stars in cataclysmic variables (CVs) are key to our understanding of the origin, evolution and behaviour of this class of interacting binary. In seeking a fuller unde…
Stokes imaging, Doppler mapping and Roche tomography of the AM Her system V834 Cen
Stephen B. Potter, E. Romero-Colmenero, C. A. Watson +2
We report on new simultaneous phase resolved spectroscopic and polarimetric observations of the polar (AM Herculis star) V834 Cen during a high state of accretion. Strong emission…
ULTRACAM photometry of the eclipsing cataclysmic variable OU Vir
W. J. Feline, V. S. Dhillon, T. R. Marsh +3
We present high-speed, three-colour photometry of the faint eclipsing cataclysmic variable OU Vir. For the first time in OU Vir, separate eclipses of the white dwarf and bright spo…
Roche tomography of cataclysmic variables -- II. Images of the secondary stars in AM Her, QQ Vul, IP Peg and HU Aqr
C. A. Watson, V. S. Dhillon, R. G. M. Rutten +1
We present a set of Roche tomography reconstructions of the secondary stars in the cataclysmic variables AM Her, QQ Vul, IP Peg and HU Aqr. The image reconstructions show distinct…
