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…
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…
The mass and radius of the M-dwarf in the short period eclipsing binary RR Caeli
P. F. L. Maxted, D. O'Donoghue, L. Morales-Rueda +1
We present new photometry and spectroscopy of the eclipsing white dwarf - M-dwarf binary star RR Cae. We use timings of the primary eclipse from white-light photo-electric photomet…
WASP-1b and WASP-2b: Two new transiting exoplanets detected with SuperWASP and SOPHIE

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 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…
Survival of a brown dwarf after engulfment by a red giant star
P. F. L. Maxted, R. Napiwotzki, P. D. Dobbie +1
(Summary of paper) High resolution optical spectroscopy of the white dwarf WD0137-349 reveals a weak Halpha line in emission, due to a low mass companion in a close orbit. Using th…
Subdwarf B binaries in the Edinburgh-Cape Survey
L. Morales-Rueda, P. F. L. Maxted, T. R. Marsh +2
We give an update of the results of a campaign to obtain orbital solutions of subdwarf B stars from the Edinburgh-Cape survey (Stobie et al. 1997). To date we have obtained blue sp…
