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…
Orbital periods of cataclysmic variables identified by the SDSS. V. VLT, NTT and Magellan observations of nine equatorial systems
John Southworth, B T Gaensicke, T R Marsh +6
We present VLT and Magellan spectroscopy and NTT photometry of nine faint cataclysmic variables (CVs) which were spectroscopically identified by the SDSS. We measure orbital period…
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…
On the Nature of Ultra-Luminous X-ray Sources from Optical/IR Measurements
Mark Cropper, Christopher Copperwheat, Kinwah Wu +1
We present a model for the prediction of the optical/infra-red emission from ULXs. In the model, ULXs are binary systems with accretion taking place through Roche lobe overflow. We…
Irradiation models for ULXs and fits to optical data
C. M. Copperwheat, M. Cropper, R. Soria +1
We have constructed a model which describes the optical emission from ultraluminous X-ray sources (ULXs), and have used it to constrain the parameters of seven ULX systems. Our mod…
