Time averaged radial spatial power spectra (top row) of the kinetic (blue lines) and magnetic (red) energies at τ = 1 for the SSD runs of the three stars (different columns). In dashed lines we show the curve a × f^–5/3 (Kolmogorov power law, where a is a constant), where f is the radial spatial frequency. The ratio of the spatial power spectra of the magnetic energy and the spatial power spectra of the kinetic energy is shown in the bottom row.
