Impact of stellar companions on precise radial velocities
D. Cunha, P. Figueira, N. C. Santos +2
Context: With the announced arrival of instruments such as ESPRESSO one can expect that several systematic noise sources on the measurement of precise radial velocity will become t…
The CORALIE survey for southern extrasolar planets XVII. New and updated long period and massive planets
M. Marmier, D. Ségransan, S. Udry +24
Since 1998, a planet-search program around main sequence stars within 50 pc in the southern hemisphere, is carried out with the CORALIE echelle spectrograph at La Silla Observatory…
Search for giant planets in M67 I. Overview
L. Pasquini, A. Brucalassi, M. T. Ruiz +7
Precise stellar radial velocities are used to search for massive (Jupiter masses or higher) exoplanets around the stars of the open cluster M67. We aim to obtain a census of massiv…
A hot Uranus transiting the nearby M dwarf GJ3470. Detected with HARPS velocimetry. Captured in transit with TRAPPIST photometry
X. Bonfils, M. Gillon, S. Udry +15
We report on the discovery of GJ3470b, a transiting hot Uranus of mass m_p = 14.0+-1.8 Mearth, radius R_p = 4.2+-0.6 Rearth and period P=3.3371+-0.0002 day. Its host star is a near…
Overabundance of alpha-elements in exoplanet host stars
V. Zh. Adibekyan, N. C. Santos, S. G. Sousa +6
We present the results for a chemical abundance analysis between planet-hosting and stars without planets for 12 refractory elements for a total of 1111 nearby FGK dwarf stars obse…
The SOPHIE search for northern extrasolar planets. V. Follow-up of ELODIE candidates: Jupiter-analogs around Sun-like stars
I. Boisse, F. Pepe, C. Perrier +21
We present radial-velocity measurements obtained in a programs underway to search for extrasolar planets with the spectrograph SOPHIE at the 1.93-m telescope of the Haute-Provence…
Comparing HARPS and Kepler surveys: The alignment of multiple-planet systems
P. Figueira, M. Marmier, G. Boué +6
Aims. We study a subset of the planetary population characterized both by HARPS and Kepler surveys. We compare the statistical properties of planets in systems with m.sin i >5-10 M…
The HARPS search for southern extra-solar planets XXXV. Super-Earths around the M-dwarf neighbors Gl433 and Gl667C
X. Delfosse, X. Bonfils, T. Forveille +11
M dwarfs have been found to often have super-Earth planets with short orbital periods. Such stars are thus preferential targets in searches for rocky or ocean planets in the solar…
