TL;DR: In this article, the authors acknowledge financial support from the French National Research Agency (ANR) through project grant, ANR10- BLANC0504-01 and ANR-07-BLAN-0221, and the EU financial support under FP7 by starting grant.
Journal ArticleDOI
Using the Sun to estimate Earth-like planet detection capabilities - VI. Simulation of granulation and supergranulation radial velocity and photometric time series
N. Meunier,N. Meunier,Anne-Marie Lagrange,Anne-Marie Lagrange,S. Borgniet,S. Borgniet,Michel Rieutord +6 more
TL;DR: In this paper, the impact of small timescale variability on radial velocity (RV) time series is studied. But the authors do not consider the effect of supergranulation on RV times series.
Journal ArticleDOI
Variability of stellar granulation and convective blueshift with spectral type and magnetic activity. I. K and G main sequence stars
TL;DR: In this paper, the amplitude of convective blueshift is estimated as a function of the spectral type, the wavelength, and the activity level of the convective convective lines.
Journal ArticleDOI
Evidence for an additional planet in the β Pictoris system
Anne-Marie Lagrange,N. Meunier,Pascal Rubini,Miriam Keppler,Miriam Keppler,F. Galland,E. Chapellier,Eric Michel,Luis Balona,Hervé Beust,Tristan Guillot,Antoine Grandjean,S. Borgniet,Djamel Mékarnia,Paul Wilson,Paul Wilson,Paul Wilson,Flavien Kiefer,Mickael Bonnefoy,J. Lillo-Box,B. Pantoja,B. Pantoja,Matias I. Jones,D. Iglesias,L. Rodet,Matias Diaz,A. Zapata,Lyu Abe,François-Xavier Schmider +28 more
TL;DR: In this article, the authors study ten years of European Southern Observatory/High Accuracy Radial Velocity Planet Searcher (HARPS) high-resolution spectroscopic data of β Pictoris.
Journal ArticleDOI
On the correlation between Ca and Halpha solar emission and consequences for stellar activity observations
N. Meunier,Xavier Delfosse +1 more
TL;DR: In this paper, the correlation between Ca and Halpha chromospheric emission, known to be positive in the solar case, has been found to vary between -1 and 1 for other stars.
