Magnetoacoustic Waves Excitation in Self-Organized Solar Magnetic Structures

Interaction of the turbulent plasma and magnetic fields is of great interest as a key to understanding self-organization processes and dynamics of the solar magnetism. We develop 3D time-dependent radiative MHD simulations that are based on first principles and provide an important tool for uncovering the basic physical mechanisms. Our simulations are able to reproduce many observed phenomena, and, in particular, allow us to investigate spontaneous formation of coherent highly magnetized flux-robe structures that are observed as "pores" in the photosphere. The dynamical evolution of these structures is accompanied by numerous magnetoacoustic waves that are excited in subphotospheric layers and propagate into the solar atmosphere. We present analysis of the pore dynamics, and properties and excitation mechanism of the magnetoacoustic waves, as well as a comparison with observations.
