The Space Density of Post-Period Minimum Cataclysmic Variables
J. V. Hernandez Santisteban, C. Knigge, M. L. Pretorius +2
Binary evolution theory predicts that accreting white dwarfs with sub-stellar companions dominate the Galactic population of cataclysmic variables (CVs). In order to test these pre…
CC Sculptoris: A superhumping intermediate polar
P. A. Woudt, B. Warner, A. Gulbis +8
We present high speed optical, spectroscopic and Swift X-ray observations made during the dwarf nova superoutburst of CC Scl in November 2011. An orbital period of 1.383 h and supe…
The photometric period in ES Ceti
C. M. Copperwheat, T. R. Marsh, V. S. Dhillon +8
We present ULTRACAM photometry of ES Cet, an ultracompact binary with a 620s orbital period. The mass transfer in systems such as this one is thought to be driven by gravitational…
Dwarf Nova Oscillations and Quasi-Periodic Oscillations in Cataclysmic Variables - VIII. VW Hyi in outburst observed with the Southern African Large Telescope
P. A. Woudt, B. Warner, D. O'Donoghue +4
We analyse four light curves obtained at high time resolution (~ 0.1 s) with the 11-m Southern African Large Telescope, at the ends of two normal outbursts and one superoutburst of…
57 second oscillations in Nova Centauri 1986 (V842 Cen)
P. A. Woudt, B. Warner, J. Osborne +1
High speed photometry in 2008 shows that the light curve of V842 Cen possesses a coherent modulation at 56.825 s, with sidebands at 56.598 s and 57.054 s. These have appeared since…
ULTRACAM observations of two accreting white dwarf pulsators
C. M. Copperwheat, T. R. Marsh, V. S. Dhillon +6
In this paper we present high time-resolution observations of GW Librae and SDSS J161033.64-010223.3 -- two cataclysmic variables which have shown periodic variations attributed to…
