Setting New Standards with HARPS
ELODIE metallicity-biased search for transiting Hot Jupiters. II. A very hot Jupiter transiting the bright K star HD 189733
Among the 160 known exoplanets, mainly detected in large radial-velocity surveys, only 8 have a characterization of their actual mass and radius thanks to the two complementary methods of detection:Expand
The HARPS search for southern extra-solar planets - XXXI. The M-dwarf sample
Searching for planets around stars with different masses helps us to assess the outcome of planetary formation for different initial conditions. The low-mass M dwarfs are also the most frequent starsExpand
WASP-12b: The hottest transiting extrasolar planet yet discovered
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 HARPS search for southern extra-solar planets: XVIII. An Earth-mass planet in the GJ 581 planetary system
The GJ 581 planetary system was already known to harbour three planets, including two presumably rocky planets which straddle its habitable zone. We report here the detection of an additional planetExpand
Transiting exoplanets from the CoRoT space mission VIII. CoRoT-7b: the first Super-Earth with measured radius
Aims. We report the discovery of very shallow (ΔF/F ≈ 3.4× 10 −4 ), periodic dips in the light curve of an active V = 11.7 G9V star observed by the CoRoT satellite, which we interpret as caused by aExpand
An Earth-mass planet orbiting α Centauri B
The detection of an Earth-mass planet orbiting the authors' neighbour star α Centauri B, a member of the closest stellar system to the Sun, is reported. Expand
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
The HARPS search for southern extra-solar planets. XI. Super-Earths (5 and 8 M{⊕}) in a 3-planet system
This Letter reports on the detection of two super-Earth planets in the Gl 581 system, which is already known to harbour a hot Neptune. One of the planets has a mass of 5 M⊕ and resides at the “warm”Expand
The HARPS search for southern extra-solar planets - VI. A Neptune-mass planet around the nearby M dwarf Gl 581
We report the discovery of a Neptune-mass planet around Gl 581 (M3V, M = 0.31 ), based on precise Doppler measurements with the HARPS spectrograph at La Silla Observatory. The radial velocitiesExpand
