Notes. The columns from left to right indicate normalised kinematic viscosity ; normalised magnetic diffusivity ; cycle periods, and their standard deviations, both in terms of tff; and energy densities if applicable. The magnetic energy density is Emag = ⟨B2/2μ0⟩, where the brackets indicate volume and time average within the radius of the star. The kinetic energy density is . The energy density for the azimuthally averaged toroidal and poloidal fields are given by and , respectively. The energy density for the differential rotation and meridional circulation are given by and , respectively. Tildes over energies refer to normalisation by Ekin; ( * ) Runs with no dynamo.

Current usage metrics show cumulative count of Article Views (full-text article views including HTML views, PDF and ePub downloads, according to the available data) and Abstracts Views on Vision4Press platform.

Data correspond to usage on the plateform after 2015. The current usage metrics is available 48-96 hours after online publication and is updated daily on week days.

Initial download of the metrics may take a while.
