Left: magnetic ratio between the squared toroidal, B_tor, and poloidal, B_pol, components near the surface. Two observational fits (dashed black for M > 0.5 M_⊙ and dotted lines for M < 0.5 M_⊙) from See et al. (2015) are indicated, as well as the fit of the simulations (purple line) and their respective error bars. Right: same ratio within the convective envelope. The coloured symbols have the following meanings: red, yellow, green, and blue represent stars with 0.5, 0.7, 0.9, and 1.1 M_⊙, respectively, and triangle, diamond, square, and filled circle shapes the rotation rates for, respectively, slow (the exact value depends on mass see Brun et al. 2022), one, three, and five times the solar rotation rate, Ω_⊙. The error bars indicate the minimum and maximum values reached by the model during the integrated time (one or several cycle periods) used to compute the mean value indicated by the symbol.
