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 angular sizes of dwarf stars and subgiants Surface brightness relations calibrated by interferometry
- P. Kervella, F. Th'evenin, E. D. Folco, D. S'egransan
- Physics
- 8 April 2004
The availability of a number of new interferometric measurements of Main Sequence and subgiant stars makes it possible to calibrate the surface brightness relations of these stars using exclusively… 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 XXXIV. Occurrence, mass distribution and orbital properties of super-Earths and Neptune-mass planets ?
- M. Mayor, M. Marmier, +11 authors N. Santos
- Physics
- 12 September 2011
Aims. We report on the results of an 8-year survey carried out at the La Silla Observatory with the HARPS spectrograph to detect and characterize planets in the super-Earth and Neptune mass regime.… Expand
An Earth-mass planet orbiting α Centauri B

- Physics, Medicine
- Nature
- 8 November 2012
Exoplanets down to the size of Earth have been found, but not in the habitable zone—that is, at a distance from the parent star at which water, if present, would be liquid. There are planets in the… Expand
The HARPS search for Earth-like planets in the habitable zone - I. Very low-mass planets around HD 20794, HD 85512, and HD 192310
Context. In 2009 we started an intense radial-velocity monitoring of a few nearby, slowly-rotating and quiet solar-type stars within the dedicated HARPS-Upgrade GTO program. Aims. The goal of this… Expand
An orbital period of 0.94 days for the hot-Jupiter planet WASP-18b
- C. Hellier, D. Anderson, +20 authors P. Wheatley
- Physics, Medicine
- Nature
- 27 August 2009
The ‘hot Jupiters’ that abound in lists of known extrasolar planets are thought to have formed far from their host stars, but migrate inwards through interactions with the proto-planetary disk from… 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
WASP-19b: The Shortest Period Transiting Exoplanet Yet Discovered
- L. Hebb, A.Collier-Cameron, +19 authors P. Wheatley
- Physics
- 3 January 2010
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
VLTI near-IR interferometric observations of Vega-like stars: Radius and age of a PsA, b Leo, b Pic, e Eri and t Cet
- E. D. Folco, F. Thévenin, +5 authors P. Morel
- Physics
- 1 November 2004
We report in this paper the direct interferometric measurement of the angular diameter of five nearby Vega-like stars: α PsA, β Leo, β Pic, � Eri and τ Cet. The near-infrared (K and H bands)… Expand
