Solar-like oscillations in the G8 V star τ Ceti
T. C. Teixeira,T. C. Teixeira,Hans Kjeldsen,Timothy R. Bedding,François Bouchy,Joergen Christensen-Dalsgaard,Margarida S. Cunha,T. H. Dall,S. Frandsen,Christoffer Karoff,Mário J. P. F. G. Monteiro,Frank P. Pijpers,Frank P. Pijpers +12 more
TL;DR: In this article, the authors used HARPS to measure oscillations in the low-mass star τ Cet. Although the data were compromised by instrumental noise, they were able to extract the main features of the oscillations.
Journal ArticleDOI
Photodynamical mass determination of the multiplanetary system K2-19

Martinez,James McCormac,C. Moutou,A. S. Rajpurohit,Jean-Pierre Rivet,Jessica Spake,Olga Suarez,D. Toublanc,Susan Walker +34 more
TL;DR: In this paper, the second multiplanetary system discovered with K2 observations, K2-19-19b, was used to detect the chopping signal of the dynamic interaction of the planets that in turn permits to uniquely characterize the system.
Journal ArticleDOI
Asteroseismology of Centauri A - Evidence of rotational splitting
Michael Bazot,Michael Bazot,François Bouchy,François Bouchy,Hans Kjeldsen,Stéphane Charpinet,M. Laymand,Sylvie Vauclair +7 more
TL;DR: In this article, the authors performed high-precision radial-velocity sequences and computed the acoustic spectrum of the star? Cen A to identify 34 p modes with angular degree l = 0-3 in the frequency range 1.8-2.
XXII. Multiple planet systems from the HARPS volume limited sample
G. Lo Curto,M. Mayor,François Bouchy,C. Moutou,Dominique Naef,Francesco Pepe,D. Segransan,Stéphane Udry +7 more
TL;DR: In this article, the authors presented the detections of three multiple systems within the HARPS volume-limited sample, including a super-Earth with a minimum mass of 6.6 MEarth and a Neptune with a mass of 18 MEarth, both orbiting their parent stars within a distance of 0.05 AU.
Journal ArticleDOI
Stellar activity of planetary host star HD 189733
Isabelle Boisse,C. Moutou,Alfred Vidal-Madjar,François Bouchy,Frederic Pont,Guillaume Hébrard,X. Bonfils,Xavier Delfosse,M. Desort,Thierry Forveille,Anne-Marie Lagrange,B. Loeillet,C. Lovis,M. Mayor,Francesco Pepe,C. Perrier,D. Queloz,Nuno C. Santos,Damien Ségransan,Stéphane Udry +19 more
TL;DR: In this article, the authors compared the variability of activity spectroscopic indices (HeI, Hα, Ca II H&K lines) to the evolution of the RV residuals and the shape of spectral lines and used such correlations to correct for the RV jitter due to stellar activity.
