We present precise z-band photometric time series spanning times of transit of the two exoplanets recently discovered by the SuperWASP collaboration. We find planetary radii of 1:44 � 0:08 and 1:04 � 0:06 RJ for WASP-1b and WASP-2b, respectively. These error estimates include both random errors in the photometry and also the uncertainty in the stellar masses. Our results are 5 times more precise than the values derived from the discovery data alone. Our measurement of the radius of WASP-2b…

Photometric observation of the transiting exoplanet WASP-1b
Abstract The extra-solar planet WASP-1b, discovered by SuperWASP consortium in 2006, was observed through R filter using the 1-meter telescope with CCD camera at Yunnan Observatory on November 11,
THE TRANSIT LIGHT CURVE PROJECT. VII. THE NOT-SO-BLOATED EXOPLANET HAT-P-1b
We present photometry of the G0 star HAT-P-1 during six transits of its close-in giant planet, and we refine the estimates of the system parameters. Relative to Jupiter's properties, HAT-P-1b is 1.20
High-precision photometry by telescope defocussing - II. The transiting planetary system WASP-4
We present high-precision photometry of two transit events of the extrasolar planetary system WASP-5, obtained with the Danish 1.54 m telescope at ESO La Silla. In order to minimise both random and
TrES-4: A Transiting Hot Jupiter of Very Low Density
We report the discovery of TrES-4, a hot Jupiter that transits the star GSC 02620-00648 every 3.55 days. From high-resolution spectroscopy of the star, we estimate a stellar effective temperature of
SuperWASP-North extrasolar planet candidates between 3 < RA < 6
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 light curve dips on a less
WASP-1: a lithium- and metal-rich star with an oversized planet*
In this paper we present our results of a comprehensive spectroscopic analysis of WASP-1, the host star to the exoplanet WASP-1b. We derive Te = 6110 45 K, logg = 4:28 0:15, and [M/H] = 0:23 0:08,
Observations of the WASP-2 System by the APOSTLE Program
We present transit observations of the WASP-2 exoplanet system by the Apache Point Survey of Transit Lightcurves of Exoplanets (APOSTLE) program. Model fitting to these data allows us to improve
Efficient identification of exoplanetary transit candidates from SuperWASP light curves
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-aperture A camera
Improved Parameters for Extrasolar Transiting Planets
We present refined values for the physical parameters of transiting exoplanets, based on a self-consistent and uniform analysis of transit light curves and the observable properties of the host
The spin-orbit angles of the transiting exoplanets WASP-1b, WASP-24b, WASP-38b and HAT-P-8b from Rossiter-McLaughlin observations
We present observations of the Rossiter-McLaughlin effect for the transiting exoplanet systems WASP-1, WASP-24, WASP-38 and HAT-P-8, and deduce the orientations of the planetary orbits with respect
