Snapshots of the Mach number on the 512³ grid at t/τ_conv = 22. The panels on the left show results from the purely hydrodynamic simulation, while the panels on the right show the MHD simulation. The upper row shows vertical cuts taken in the z = 0 plane, while the lower row shows a horizontal cut through the y = 1.5 L_ref plane. The white-dotted line indicates the initial position of the convective boundary.
