Acoustic wave propagation in the solar sub-photosphere with localised magnetic field concentration: effect of magnetic tension
Acoustic wave propagation in the solar sub-photosphere with localised magnetic field concentration: effect of magnetic tension
<i>Aims. <i/>We analyse numerically the propagation and dispersion of acoustic waves in the solar-like sub-photosphere with localised non-uniform magnetic field concentrations, mimicking sunspots with various representative magnetic field configurations.<i>Methods. <i/>Numerical simulations of wave propagation through the solar sub-photosphere with a localised magnetic field concentration are carried out using SAC, which …
