The CARMENES search for exoplanets around M dwarfs: Radial-velocity variations of active stars in visual-channel spectra

L. Tal-Or, M. Zechmeister, A. Reiners +22

Previous simulations predicted the activity-induced radial-velocity (RV) variations of M dwarfs to range from $\sim 1$ cm/s to $\sim 1$ km/s, depending on various stellar and activit…
