A substellar component orbiting the F-star 30 Ari B
E. W. Guenther, M. Hartmann, M. Esposito +3
CONTEXT: Most current radial velocity planet search programs have concentrated on stars of one solar mass. Our knowledge on the frequency of giant planets and brown dwarf companion…
The HARPS search for southern extra-solar planets. XX. Planets around the active star BD-08:2823
G. Hebrard, S. Udry, G. Lo Curto +13
We report the detection of a planetary system around BD-08:2823, that includes at least one Uranus-mass planet and one Saturn-mass planet. This discovery serendipitously originates…
Radial Velocities with CRIRES: Pushing precision down to 5-10 m/s
P. Figueira, F. Pepe, C. H. F. Melo +6
With the advent of high-resolution infrared spectrographs, Radial Velocity (RV) searches enter into a new domain. As of today, the most important technical question to address is w…
Unprecedented accurate abundances: signatures of other Earths?
J. Melendez, M. Asplund, B. Gustafsson +2
For more than 140 years the chemical composition of our Sun has been considered typical of solar-type stars. Our highly differential elemental abundance analysis of unprecedented a…
Spin-orbit misalignment in the HD80606 planetary system
F. Pont, G. Hebrard, J. M. Irwin +5
We recently reported the photometric and spectroscopic detection of the primary transit of the 111-day-period, eccentric extra-solar planet HD80606 b, at Observatoire de Haute-Prov…
The HARPS search for southern extra-solar planets XVIII. An Earth-mass planet in the GJ 581 planetary system
M. Mayor, X. Bonfils, T. Forveille +10
The GJ 581 planetary system was already known to harbour three planets, including two super-Earths planets which straddle its habitable zone. We report here the detection of an add…
