Journal ArticleDOI
The CORALIE survey for southern extra-solar planets VII. Two short-period Saturnian companions to HD108147 and HD168746
Francesco Pepe,M. Mayor,F. Galland,Dominique Naef,D. Queloz,Nuno C. Santos,Stéphane Udry,M. Burnet +7 more
TL;DR: In this article, the authors presented the discovery of two Saturn-mass companions to HD108147 and HD168746 by means of the CORALIE echelle spectrograph.
Journal ArticleDOI
The HARPS search for southern extra-solar planets - XVII. Super-Earth and Neptune-mass planets in multiple planet systems HD 47 186 and HD 181 433
François Bouchy,Michel Mayor,C. Lovis,Stéphane Udry,Willy Benz,Jean-Loup Bertaux,X. Delfosse,C. Mordasini,Francesco Pepe,D. Queloz,Damien Ségransan +10 more
TL;DR: In this article, the authors reported the detection of two new multiple planet systems orbiting solar-like stars HD 47 186 and HD 181 433, which increased to 20 the number of close-in low-mass exoplanets (below 0.1 M JUP) and strengthen the fact that 80% of these planets are in multiple planetary systems.
Journal ArticleDOI
The HARPS search for southern extra-solar planets XI. Super-Earths (5 & 8 M_Earth) in a 3-planet system
Stéphane Udry,X. Bonfils,X. Delfosse,T. Forveille,M. Mayor,C. Perrier,François Bouchy,C. Lovis,Francesco Pepe,D. Queloz,Jean-Loup Bertaux +10 more
TL;DR: In this article, the authors reported the detection of two super-Earth planets in the Gl581 system, already known to harbour a hot Neptune, and confirmed the previously tentative statistical trend for many more very low-mass planets being found around M dwarfs than around solar-type stars.

The HARPS search for southern extra-solar planets ? XI. Super-Earths (5&8M ) in a 3-planet system
Stéphane Udry,X. Bonfils,X. Delfosse,T. Forveille,Michel Mayor,C. Perrier,Francois Bouchy,C. Lovis,Francesco Pepe,D. Queloz +9 more
TL;DR: In this article, the authors reported the detection of two super-Earth planets in the Gl 581 system, which is known to harbor a hot Neptune and has a mass of 5.7 M and orbits at 0.25 AU from the star.
Journal ArticleDOI
Fundamental photon noise limit to radial velocity measurements
TL;DR: In this paper, the fundamental limit of radial velocity measurement given by photon noise is presented and illustrated with a representative sample of synthetic solar-type stellar spectra, which is applied to two dedicated spectrographs.
