The Geneva-Copenhagen survey of the Solar neighbourhood. Ages, metallicities, and kinematic properti
We present and discuss new determinations of metallicity, rotation, age, kinematics, and Galactic orbits for a com- plete, magnitude-limited, and kinematically unbiased sample of 16 682 nearby F and
A Jupiter-mass companion to a solar-type star
The presence of a Jupiter-mass companion to the star 51 Pegasi is inferred from observations of periodic variations in the star's radial velocity. The companion lies only about eight million
Setting New Standards with HARPS
A super-Earth transiting a nearby low-mass star
Observations of the transiting planet GJ’1214b are reported, finding that the planetary mass and radius are consistent with a composition of primarily water enshrouded by a hydrogen–helium envelope that is only 0.05% of the mass of the planet.
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:
ELODIE: A spectrograph for accurate radial velocity measurements
The bre{fed echelle spectrograph of Observatoire de Haute{Provence, ELODIE, is presented. This instrument has been in operation since the end of 1993 on the 1.93 m telescope. ELODIE is designed as an
An extended upper atmosphere around the extrasolar planet HD209458b
The detection of atomic hydrogen absorption in the stellar Lyman α line during three transits of HD209458b is reported, showing that this absorption should take place beyond the Roche limit and therefore can be understood in terms of escaping hydrogen atoms.
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 stars
The Geneva–Copenhagen Survey of the Solar Neighbourhood
Abstract We report on a new survey of metallicities, ages, and Galactic orbits for a complete, magnitude-limited, and kinematically unbiased all-sky sample of 16 682 nearby F- and G-dwarfs. Our ∼ 63
Chemical abundances of 1111 FGK stars from the HARPS GTO planet search program - Galactic stellar populations and planets
Context. We performed a uniform and detailed abundance analysis of 12 refractory elements (Na, Mg, Al, Si, Ca, Ti, Cr, Ni, Co, Sc, Mn, and V) for a sample of 1111 FGK dwarf stars from the HARPS GTO
