Investigating stellar activity through eight years of Sun-as-a-star observations
Baptiste Klein, Suzanne Aigrain, Michael Cretignier +11
Stellar magnetic activity induces both distortions and Doppler-shifts in the absorption line profiles of Sun-like stars. Those effects produce apparent radial velocity (RV) signals…
Confrontation between modelled solar integrated observables and direct observations I. Radial velocities and convective blueshift
Nadège Meunier, Anne-Marie Lagrange, Xavier Dumusque +1
Stellar variability strongly impacts the search for low-mass exoplanets with radial velocity techniques. Two types of planet-free time series can be used to quantify this impact: m…
Characterisation of the stellar activity of M dwarfs. II. Relationship between Ca, H, and Na chromospheric emissions
Nadège Meunier, Lucile Mignon, Matthieu Kretzschmar +1
The chromospheric emission estimated in the core of different lines, such as Ca II H & K, Na D1 and D2, and Halpha, is not always correlated between lines, as the Ca II H & K and H…
