Solar and stellar activity cycles – no synchronization with exoplanets

Cyclic activity on the Sun and stars is primarily explained by generation of magnetic field a dynamo mechanism, which converts energy poloidal into toroidal component due to differential rotation. There is, however, an alternative point view, explains gravitational influence planetary system and, first all, Jupiter. This hypothesis can be verified comparing characteristics exoplanets with variations their associated stars. We have performed such comparison drawn negative conclusion. No relationship between cycle host star could found in any cases considered. Moreover, there are reasons believe that strong may completely eliminate cyclic variation stellar activity.
