WASP-12b: The hottest transiting extrasolar planet yet discovered
TLDR
The planet has an equilibrium temperature of T eq = 2516 K caused by its very short period orbit around the hot, twelfth magnitude host star and has the largest radius of any transiting planet yet detected. Expand
The WASP project and the superWASP cameras
ABSTRACT The SuperWASP cameras are wide‐field imaging systems at the Observatorio del Roque de los Muchachos on the island of La Palma in the Canary Islands, and at the Sutherland Station of theExpand
The HARPS search for southern extra-solar planets
Context. We present radial-velocity measurements of eight stars observed with the HARPS Echelle spectrograph mounted on the 3.6-m telescope in La Silla (ESO, Chile). Data span more than ten years andExpand
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 =Expand
An orbital period of 0.94 days for the hot-Jupiter planet WASP-18b
TLDR
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. Expand
Line-profile tomography of exoplanet transits - II. A gas-giant planet transiting a rapidly rotating A5 star
TLDR
Photometry and time-series spectroscopy through three separate transits are used to confirm the existence of a gas-giant planet with an orbital period of 1.22 d in orbit around HD 15082, and opens the way to studying the formation of planets around a whole new class of young, early-type stars, hence under different physical conditions and generally in an earlier stage of formation than in sharp-lined late- type stars.

The PLATO 2.0 mission
PLATO 2.0 has recently been selected for ESA’s M3 launch opportunity (2022/24). Providing accurate key planet parameters (radius, mass, density and age) in statistical numbers, it addressesExpand
The Hα Galaxy Survey ⋆ I. The galaxy sample, Hα narrow-band observations and star formation parameters for 334 galaxies
We discuss the selection and observations of a large sample of nearby galaxies, which we are using to quantify the star formation activity in the local Universe. The sample consists of 334 galaxiesExpand
The Mass of Kepler-93b and The Composition of Terrestrial Planets
Kepler-93b is a 1.478 ± 0.019 R⊕ planet with a 4.7 day period around a bright (V = 10.2), astroseismically characterized host star with a mass of 0.911 ± 0.033 Mand a radius of 0.919 ± 0.011 R� .Expand
Stellar rotation in the Hyades and Praesepe: gyrochronology and braking time-scale
We present the results of photometric surveys for stellar rotation in the Hyades and in Praesepe, using data obtained as part of the SuperWASP exoplanetary transit-search programme. We determinedExpand
