    Theoretical Modeling of Propagation of Magnetoacoustic Waves in Magnetic Regions Below Sunspots
    We use two-dimensional numerical simulations and eikonal approximation to study properties of magnetohydrodynamic (MHD) waves traveling below the solar surface...

    Tracing p-mode Waves from the Photosphere to the Corona in Active Regions
    Atmosphere above sunspots is abundant with different types of waves. Among these waves are running penumbral waves in the chromosphere, quasi-periodic...
