Driven two-fluid slow magnetoacoustic waves in the solar chromosphere with a realistic ionisation profile

<p>An animation showing log(Ti) overlaid by magnetic field lines. The initial atmosphere (at t = 0 s) is described by a hydrostatic equilibrium supplemented by the Saha equation and embedded in a fanning magnetic field. This initial equilibrium is perturbed by a monochromatic driver which operates in the chromosphere on the vertical components of the ion and neutral velocities with period P = 5 s.</p>
