- Nature
- 16 December 2009
A decade ago, the detection of the first transiting extrasolar planet provided a direct constraint on its composition and opened the door to spectroscopic investigations of extrasolar planetary… Expand
The HARPS search for southern extra-solar planets - XXXI. The M-dwarf sample
- X. Bonfils, X. Delfosse, +11 authors J. Bertaux
- Physics
- 21 November 2011
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 stars… Expand
The HARPS search for southern extra-solar planets: XVIII. An Earth-mass planet in the GJ 581 planetary system
- M. Mayor, X. Bonfils, +10 authors N. Santos
- Physics
- 15 June 2009
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 planet… Expand
The HARPS search for southern extra-solar planets. XI. Super-Earths (5 and 8 M{⊕}) in a 3-planet system
- S. Udry, X. Bonfils, +19 authors Verrieres-le-Buisson
- Physics
- 29 April 2007
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
- X. Bonfils, T. Forveille, +7 authors J. Bertaux
- Physics
- 8 September 2005
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 velocities… Expand
Metallicity of M dwarfs - I. A photometric calibration and the impact on the mass-luminosity relation at the bottom of the main sequence
- X. Bonfils, X. Delfosse, S. Udry, N. Santos, T. Forveille, D. S'egransan
- Physics
- 11 March 2005
We obtained high resolution ELODIE and CORALIE spectra for both components of 20 wide visual binaries composed of an F-, G- or K-dwarf primary and an M-dwarf secondary. We analyse the well-understood… Expand
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 addresses… Expand
Accurate Spitzer infrared radius measurement for the hot Neptune GJ 436b
- M. Gillon, B.-O. Demory, +25 authors Israel.
- Physics
- 16 July 2007
We present Spitzer Space Telescope infrared photometry of a primary transit of the hot Neptune GJ 436b. The observations were obtained using the 8 µm band of the InfraRed Array Camera (IRAC). The… Expand
PIONIER: a 4-telescope visitor instrument at VLTI

- Physics
- 9 September 2011
PIONIER stands for Precision Integrated-Optics Near-infrared Imaging ExpeRiment. It combines four 1.8m Auxilliary Telescopes or four 8m Unit Telescopes of the Very Large Telescope Interferometer… Expand
