Time series and PDS of three simulations from Rodríguez Díaz et al. (2022), as a reformatted version of their Fig. 3. The time series are plotted as a function of convective turnover times and coloured as indicated by the legend. For each PDS, the raw spectrum is shown in grey with a binned version overplotted in black. The vertical dashed lines indicate the values of ν_max ≃ 3094, 363, 12.7 μHz for the solar, SGB, and RGB simulations, respectively.
