Fig. 6.
From top to bottom: radial velocity, Hα line flux, and average longitudinal magnetic field as a function of Julian date (left) and rotational phase (right). The sinusoidal fit, forced at the K2 photometric period, to radial velocity variations is shown as a black dash-dotted curve in the top panels. The Bl = 0 G line is drawn for reference in the bottom panels.
