A much lower density for the transiting extrasolar planet WASP-7
John Southworth, M. Dominik, U. G. Jorgensen +29
We present the first high-precision photometry of the transiting extrasolar planetary system WASP-7, obtained using telescope defocussing techniques and reaching a scatter of 0.68…
The WASP-South search for transiting exoplanets
Coel Hellier, D. R. Anderson, A. Collier Cameron +9
Since 2006 WASP-South has been scanning the Southern sky for transiting exoplanets. Combined with Geneva Observatory radial velocities we have so far found over 30 transiting exopl…
WASP-34b: a near-grazing transiting sub-Jupiter-mass exoplanet in a hierarchical triple system
B. Smalley, D. R. Anderson, A. Collier Cameron +19
We report the discovery of WASP-34b, a sub-Jupiter-mass exoplanet transiting its 10.4-magnitude solar-type host star (1SWASP J110135.89-235138.4; TYC 6636-540-1) every 4.3177 days…
WASP-41b: A transiting hot Jupiter planet orbiting a magnetically-active G8V star
P. F. L. Maxted, D. R. Anderson, A. Collier Cameron +13
We report the discovery of a transiting planet with an orbital period of 3.05d orbiting the star TYC 7247-587-1. The star, WASP-41, is a moderately bright G8V star (V=11.6) with a…
The spin-orbit angles of the transiting exoplanets WASP-1b, WASP-24b, WASP-38b and HAT-P-8b from Rossiter-McLaughlin observations
E. K. Simpson, D. Pollacco, A. Collier Cameron +18
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 or…
WASP-31b: a low-density planet transiting a metal-poor, late-F-type dwarf star
D. R. Anderson, A. Collier Cameron, C. Hellier +15
We report the discovery of the low-density, transiting giant planet WASP-31b. The planet is 0.48 Jupiter masses and 1.55 Jupiter radii. It is in a 3.4-day orbit around a metal-poor…
