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…
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…
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
We report on observations of 11 transit events of the transiting extrasolar planet XO-1b by the SuperWASP-North observatory. From our data, obtained during May-September 2004, we f…
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-ray behaviour of Circinus X-1 - I: X-ray Dips as a diagnostic of periodic behaviour
W. I. Clarkson, P. A. Charles, N. Onyett
We examine the periodic nature of detailed structure (particularly dips) in the RXTE/ASM lightcurve of Circinus X-1. The significant phase wandering of the X-ray maxima suggests th…
Long-term Properties of Accretion Disks in X-ray Binaries: I. the variable third period in SMC X-1
W. I. Clarkson, P. A. Charles, M. J. Coe +3
Long term X-ray monitoring data from the RXTE ASM and CGRO BATSE reveal that the third (superorbital) period in SMC X-1 is not constant, but varies between 40-60 days. A dynamic po…
X-ray and UV Variability in the Core of M15: the nature of X2127+119/AC211
P. A. Charles, W. I. Clarkson, L. van Zyl
The prototypical post-core-collapse globular cluster M15 provides an ideal environment for the formation of exotic binaries, it being already known to contain a luminous LMXB (X212…
