Orbital periods of cataclysmic variables identified by the SDSS. VII. Four new eclipsing systems
John Southworth, C. M. Copperwheat, B T Gansicke +1
We present photometry of nine cataclysmic variable stars identified by the Sloan Digital Sky Survey, aimed at measuring the orbital periods of these systems. Four of these objects…
Physical properties of IP Pegasi: an eclipsing dwarf nova with an unusually cool white dwarf
C. M. Copperwheat, T. R. Marsh, V. S. Dhillon +4
We present high speed photometric observations of the eclipsing dwarf nova IP Peg taken with the triple-beam camera ULTRACAM mounted on the William Herschel Telescope. The primary…
Precise mass and radius values for the white dwarf and low mass M dwarf in the pre-cataclysmic binary NN Serpentis
S. G. Parsons, T. R. Marsh, C. M. Copperwheat +4
We derive precise system parameters for the pre-cataclysmic binary, NN Ser. From light curve fitting we find an orbital inclination of i = 89.6 +/- 0.2 deg. From the HeII absorptio…
A Stellar Flare during the Transit of the Extrasolar Planet OGLE-TR-10b
Samuel Bentley, Coel Hellier, Pierre Maxted +4
We report a stellar flare occurring during a transit of the exoplanet OGLE-TR-10b, an event not previously reported in the literature. This reduces the observed transit depth, part…
Hunting high and low: XMM monitoring of the eclipsing polar HU Aquarii
R. Schwarz, A. D. Schwope, J. Vogel +5
We want to study the temporal and spectral behaviour of HU Aqr in the X-ray domain during different accretion states. We obtained spectra and light curves from four different XMM-N…
Optical pulsations from the anomalous X-ray pulsar 1E 1048.1-5937
V. S. Dhillon, T. R. Marsh, S. P. Littlefair +7
We present high-speed optical photometry of the anomalous X-ray pulsar 1E 1048.1-5937 obtained with ULTRACAM on the 8.2-m Very Large Telescope in June 2007. We detect 1E 1048.1-593…
