Magnetic cycles and activity in FGK stars in the framework of Babcock-Leighton dynamos

Motivated by the data on long-term stellar magnetic activity variations, and by the recent success of Babcock-Leighton type flux-transport dynamos in explaining many large-scale solar cycle features, we explore the viability of a similar dynamo in G stars over a wide range of rotation rates (Omega(circle dot) less than or equal to Omega less than or equal to 100Omega(circle dot)). We show that with suitable scaling of the differential rotation, meridional circulation, surface poloidal source term, and turbulent diffusion, this class of model correctly predicts that faster rotators should produce more magnetic flux and have shorter cycle periods than slower rotators, as observed. We also explore how the cycle period in such models may vary in stars cooler than the Sun.
