Meridional flow velocities for solar-like stars with known activity cycles

Abstract

The direct measurements of the meridional flow velocities on stars are impossible today. We suppose that the matter on a surface of solar-like stars with stable activity period passes the way equal to 2π R*- during the stellar Hale cycle. We present here the dependence of meridional flow velocity on Rossby number, which is an effective parameter of the stellar magnetic dynamo. © International Astronomical Union 2014.
