The mass of the neutron star in SMC X-1
A. K. F. Val Baker, A. J. Norton, H. Quaintrell
We present new optical spectroscopy of the eclipsing binary pulsar Sk 160/SMC X-1. From the He I absorption lines, taking heating corrections into account, we determine the radial…
Current Status of the SuperWASP Project
D. J. Christian, D. L. Pollacco, W. I. Clarkson +16
We present the current status of the SuperWASP project, a Wide Angle Search for Planets. SuperWASP consists of up to 8 individual cameras using ultra-wide field lenses backed by hi…
X-rays from Cataclysmic Variables
Erik Kuulkers, Andrew Norton, Axel Schwope +1
Cataclysmic Variables are a distinct class of interacting binaries, transferring mass from a donor star to a degenerate accretor, a white dwarf. We here review X-ray observations o…
Multiwavelength observations revealing the outbursts of the two soft X-ray transients XTE J1859+226 and XTE J1118+480
S. Chaty, C. A. Haswell, R. I. Hynes +9
We report here on multiwavelength observations of the two new soft X-ray transients (SXTs) XTE J1859+226 and XTE J1118+480, which we observed with HST/RXTE/UKIRT. For XTE J1118+480…
YY Draconis and V709 Cassiopeiae: two intermediate polars with weak magnetic fields
A. J. Norton, A. P. Beardmore, Alasdair Allan +1
We present data from long ROSAT HRI observations of the intermediate polars YY Dra and V709 Cas which show that V709 Cas, like YY Dra, exhibits a double-peaked X-ray pulse profile.…
Is TW Pictoris really an intermediate polar?
A. J. Norton, A. P. Beardmore
We present the results of a long ROSAT HRI observation of the candidate intermediate polar TW Pic. The power spectrum shows no sign of either the previously proposed white dwarf sp…
