Planets around evolved intermediate-mass stars III. Planet candidates and long-term activity signals in six open clusters
E. Delgado Mena, J. Gomes da Silva, J. P. Faria +6
[abridged]The aim of this work is to search for planets around evolved stars, with a special focus on stars more massive than 2\,M in light of previous findings that show a…
: a data-driven approach to correct for systematics in RV data -- Application to SPIRou data of the planet-hosting M dwarf GJ 251
M. Ould-Elhkim, C. Moutou, J-F. Donati +18
Context: Recent advances in the development of precise radial velocity (RV) instruments in the near-infrared (nIR) domain, such as SPIRou, have facilitated the study of M-type star…
Optical and near-infrared stellar activity characterization of the early M dwarf Gl~205 with SOPHIE and SPIRou
P. Cortes-Zuleta, I. Boisse, B. Klein +41
The stellar activity of M dwarfs is the main limitation for discovering and characterizing exoplanets orbiting them since it induces quasi-periodic RV variations. We aim to charact…
