Predicting convective blueshift and radial-velocity dispersion due to granulation for FGK stars
S. Dalal, R. D. Haywood, A. Mortier +2
To detect Earth-mass planets using the Doppler method, a major obstacle is to differentiate the planetary signal from intrinsic stellar variability (e.g., pulsations, granulation,…
Activity time series of old stars from late F to early K VI. Exoplanet mass characterisation and detectability in radial velocity
Nadège Meunier, Romain Pous, Sophia Sulis +2
Stellar variability impacts radial velocities at various timescales and therefore the detectability of exoplanets and the mass determination based on this technique. It is necessar…
Preparing an unsupervised massive analysis of SPHERE high contrast data with the PACO algorithm
A. Chomez, A. -M. Lagrange, P. Delorme +9
We aim at searching for exoplanets on the whole ESO/VLT-SPHERE archive with improved and unsupervised data analysis algorithm that could allow to detect massive giant planets at 5…
On the radial distribution of giant exoplanets at Solar System scales
A. -M. Lagrange, F. Philipot, P. Rubini +5
Context. Giant planets play a major role in multiple planetary systems. Knowing their demographics is important to test their overall impact on planetary systems formation. It is a…
Characterisation of stellar activity of M dwarfs. I. Long-timescale variability in a large sample and detection of new cycles
L. Mignon, N. Meunier, X. Delfosse +7
M dwarfs are active stars that exhibit variability in chromospheric emission and photometry at short and long timescales, including long cycles that are related to dynamo processes…
A HARPS radial velocity search for planets in the Scorpius-Centaurus association. And its combination with the HARPS and SOPHIE young nearby stars (YNS) surveys
Antoine Grandjean, A. -M. Lagrange, N. Meunier +13
The Scorpius-Centaurus (Sco-Cen) young and nearby massive star-forming region is particularly well suited for extrasolar planet searches with both direct imaging and radial velocit…
