Normalized perturbations of the longitudinal component of velocity (top row), density (middle row), and temperature (bottom row) from simulations of Alfvén waves (left column), ion-cyclotron waves (center column), and whistler waves (right column) with a period of τ = 0.02 s and driving amplitude A_c = 0.01 c_A,T. Case of a plasma with n_p = 1.4 × 10¹⁵ m⁻³, χ = 100, B₀ = 10 G, and ν_nc = 100ω. The red solid lines correspond to the results for the charged fluid, while the blue dashed lines represent the results for the neutral fluid, computed at the time t = 15τ.
