Fig. 1
All the graphs are for HD 7199. Top panel: RVs and activity index, log(
), as a function of time. Lower panel: RVs folded in phase for the two Keplerian fitted. On the left the real planet and on the right the RV variation induced by the magnetic cycle, which is similar to the activity index variation. Thus, we see clearly that magnetic cycles induce a RV variation.
