Eigenfunctions obtained for the CU Vir model with n_Brad = +1.0. Top panels: Distribution of angular velocity, Ω(r). Bottom panels: Toroidal magnetic field component, B(r). In each row, the left panel shows the real part, and the right panel the imaginary part. The modes from the lowest to the fourth are indicated as red, blue, green, and cyan lines. The reciprocals of the eigenvalues for each mode are shown in the legend. The gray-shaded area indicates the central convective region.
