Spiral-shaped wavefronts in a sunspot umbra
T. Felipe, C. Kuckein, E. Khomenko +1
Solar active regions show a wide variety of oscillatory phenomena. The presence of the magnetic field leads to the appearance of several wave modes, whose behavior is determined by…

Height variation of the cutoff frequency in a sunspot umbra
T. Felipe, C. Kuckein, I. Thaler
In the solar atmosphere, the acoustic cutoff frequency is a local quantity which depends on the atmospheric height. It separates the low-frequency evanescent waves from the high-fr…

Small-scale dynamos on the solar surface: dependence on magnetic Prandtl number
I. Thaler, H. C. Spruit
The question of possible small-scale dynamo action in the surface layers of the Sun is revisited with realistic 3D MHD simulations. As in other MHD problems, dynamo action is found…
