WASP-19b: The Shortest Period Transiting Exoplanet Yet Discovered
We report on the discovery of a new extremely short period transiting extrasolar planet, WASP-19b. The planet has mass M pl = 1.15 ± 0.08 MJ , radius R pl = 1.31 ± 0.06 RJ , and orbital period P =
An orbital period of 0.94 days for the hot-Jupiter planet WASP-18b
Either WASP-18 is in a rare, exceptionally short-lived state, or the tidal dissipation in this system (and possibly other hot-Jupiter systems) must be much weaker than in the Solar System.
Improved parameters for the transiting hot Jupiters WASP-4b and WASP-5b
The gaseous giant planets WASP-4b and WASP-5b are transiting 12-magnitude solar-type stars in the Southern hemisphere. The aim of the present work is to refine the parameters of these systems using
Spitzer 3.6 and 4.5 μm full-orbit light curves of WASP-18
We present new light curves of the massive hot Jupiter system WASP-18 obtained with the Spitzer spacecraft covering the entire orbit at 3.6 and 4.5 μm. These light curves are used to measure the
Wasp-17b: An Ultra-Low Density Planet in a Probable Retrograde Orbit
It will be important to determine more precisely the current orbital eccentricity by further high-precision radial velocity measurements or by timing the secondary eclipse, both to reduce the uncertainty on the planet's radius and to test tidal-heating models.
The TRAPPIST survey of southern transiting planets. I. Thirty eclipses of the ultra-short period planet WASP-43 b
We present twenty-three transit light curves and seven occultation light curves for the ultra-short period planet WASP -43 b, in addition to eight new measurements of the radial velocity of the star.
Thermal emission at 4.5 and 8 μm of WASP-17b, an extremely large planet in a slightly eccentric orbit
We report the detection of thermal emission at 4.5 and 8 mu m from the planet WASP-17b. We used Spitzer to measure the system brightness at each wavelength during two occultations of the planet by
WASP-52b, WASP-58b, WASP-59b, and WASP-60b: four new transiting close-in giant planets
We present the discovery of four new transiting hot Jupiters, detected mainly from SuperWASP-North and SOPHIE observations. These new planets, WASP-52b, WASP-58b, WASP-59b, and WASP-60b, have orbital
The main-sequence rotation-colour relation in the Coma Berenices open cluster
We present the results of a photometric survey of rotation rates in the Coma Berenices (Melotte 111) open cluster, using data obtained as part of the SuperWASP exoplanetary transit-search programme.
WASP-78b and WASP-79b: two highly-bloated hot Jupiter-mass exoplanets orbiting F-type stars in Eridanus
We report the discovery of WASP-78b and WASP-79b, two highly-bloated Jupiter-mass exoplanets orbiting F-type host stars. WASP-78b orbits itsV = 12.0 host star (TYC 5889-271-1) every 2.175 days and
