The heating of the solar chromosphere by convective oscillations in weak magnetic field regions

The possibility of local energy absorption in the upper solar chromosphere, due to the dissipation of forced high-beta plasma oscillations in the cusp-resonance region, is discussed. The plasma oscillations are caused by the perturbation of the plasma boundary due to convective motions. The plasma is described by double-fluid MHD equations for the highly magnetized ions and electrons, while taking into account the dissipative effects. The heating rate of the plasma layer is calculated, and the absorption power density is obtained. The broad wavepacket provides the heating of an inhomogeneous layer in the wide region.
