We report on the discovery of WASP-12b, a new transiting extrasolar planet with and . The planet and host star propertie…
The sub-Jupiter mass transiting exoplanet WASP-11b
R. G. West, A. Collier Cameron, L. Hebb +25
We report the discovery of a sub-Jupiter mass exoplanet transiting a magnitude V=11.7 host star 1SWASP J030928.54+304024.7. A simultaneous fit to the transit photometry and radial-…
WASP-5b: a dense, very-hot Jupiter transiting a 12th-mag Southern-hemisphere star
D. R. Anderson, M. Gillon, C. Hellier +28
We report the discovery of WASP-5b, a Jupiter-mass planet orbiting a 12th-mag G-type star in the Southern hemisphere. The 1.6-d orbital period places WASP-5b in the class of very-h…
SuperWASP-N Extra-solar Planet Candidates from Fields 06hr < RA < 16hr
S. R. Kane, W. I. Clarkson, R. G. West +21
The Wide Angle Search for Planets (WASP) survey currently operates two installations, designated SuperWASP-N and SuperWASP-S, located in the northern and southern hemispheres respe…
WASP-3b: a strongly-irradiated transiting gas-giant planet
D. Pollacco, I. Skillen, A. Collier Cameron +43
We report the discovery of WASP-3b, the third transiting exoplanet to be discovered by the WASP and SOPHIE collaboration. WASP-3b transits its host star USNO-B1.0 1256-0285133 ever…
SuperWASP-North Extra-solar Planet Candidates between 3hr < RA < 6hr
W. I. Clarkson, B. Enoch, C. A. Haswell +21
The Wide Angle Search for Planets (WASP) photometrically surveys a large number of nearby stars to uncover candidate extrasolar planet systems by virtue of small-amplitude lightcur…
Efficient identification of exoplanetary transit candidates from SuperWASP light curves
A. Collier Cameron, D. M. Wilson, R. G. West +29
Transiting extrasolar planets constitute only a small fraction of the range of stellar systems found to display periodic, shallow dimmings in wide-field surveys employing small-ape…
SuperWASP-North Extrasolar Planet Candidates. Candidates from Fields 17hr < RA < 18hr
T. A. Lister, R. G. West, D. M. Wilson +22
We have performed photometric observations of nearly 7 million stars with 8 < V < 15 with the SuperWASP-North instrument from La Palma between 2004 May-September. Fields in the RA…
New periodic variable stars coincident with ROSAT sources discovered using SuperWASP
A. J. Norton, P. J. Wheatley, R. G. West +17
We present optical lightcurves of 428 periodic variable stars coincident with ROSAT X-ray sources, detected using the first run of the SuperWASP photometric survey. Only 68 of thes…
The colour of noise in SuperWASP data and the implications for finding extra-solar planets
A. M. S. Smith, A. Collier Cameron, D. J. Christian +19
A recent study demonstrated that there is significant covariance structure in the noise on data from ground-based photometric surveys designed to detect transiting extrasolar plane…
A fast hybrid algorithm for exoplanetary transit searches
A. Collier Cameron, D. Pollacco, R. A. Street +22
We present a fast and efficient hybrid algorithm for selecting exoplanetary candidates from wide-field transit surveys. Our method is based on the widely-used SysRem and Box Least-…
WASP-1b and WASP-2b: Two new transiting exoplanets detected with SuperWASP and SOPHIE
A. Collier Cameron, F. Bouchy, G. Hebrard +36
We have detected low-amplitude radial-velocity variations in two stars, USNO-B1.0 1219-0005465 (GSC 02265-00107 = WASP-1) and USNO-B1.0 0964-0543604 (GSC 00522-01199 = WASP-2). Bot…
The impact of correlated noise on SuperWASP detection rates for transiting extra-solar planets
A. M. S. Smith, A. Collier Cameron, D. J. Christian +19
We present a model of the stellar populations in the fields observed by one of the SuperWASP-N cameras in the 2004 observing season. We use the Besancon Galactic model to define th…
The WASP Project and the SuperWASP Cameras
D. L. Pollacco, I. Skillen, A. Collier Cameron +25
The SuperWASP Cameras are wide-field imaging systems sited at the Observatorio del Roque de los Muchachos on the island of La Palma in the Canary Islands, and the Sutherland Statio…
SuperWASP Observations of the Transiting Extrasolar planet XO-1b
D. M. Wilson, B. Enoch, D. J. Christian +18

The automated classification of astronomical lightcurves using Kohonen self-organising maps
David R. Brett, Richard G. West, Peter J. Wheatley
We apply the technique of self-organising maps (Kohonen 1990) to the automated classification of singly periodic astronomical lightcurves. We find that our maps readily distinguish…
Variability in black hole accretion discs
