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…
Optical variability of the ultracool dwarf TVLM 513-46546: evidence for inhomogeneous dust clouds
S. P. Littlefair, V. S. Dhillon, T. R. Marsh +3
We present multi-colour photometry of the M8.5V ultracool dwarf "pulsar" TVLM 513-46546 (hereafter TVLM 513) obtained with the triple-beam photometer ULTRACAM. Data were obtained s…
On the evolutionary status of short period cataclysmic variables
S. P. Littlefair, V. S. Dhillon, T. R. Marsh +5
(Abridged) We present high-speed, three-colour photometry of seven short period (Porb <= 95 mins) eclipsing CVs from the Sloan Digital Sky Survey. We determine the system parameter…
ULTRACAM: an ultra-fast, triple-beam CCD camera for high-speed astrophysics
V. S. Dhillon, T. R. Marsh, M. J. Stevenson +15
ULTRACAM is a portable, high-speed imaging photometer designed to study faint astronomical objects at high temporal resolutions. ULTRACAM employs two dichroic beamsplitters and thr…
A brown dwarf mass donor in an accreting binary
S. P. Littlefair, V. S. Dhillon, T. R. Marsh +3
A long standing and unverified prediction of binary star evolution theory is the existence of a population of white dwarfs accreting from sub-stellar donor stars. Such systems ough…
Empirical isochrones and relative ages for young stars, and the radiative-convective gap
N. J. Mayne, Tim Naylor, S. P. Littlefair +2
We have selected pre-main-sequence stars in 12 groups of notional ages ranging from 1 Myr to 35 Myrs, using heterogeneous membership criteria. Using these members we have construct…
