Numerical MHD Simulations of Solar Magnetoconvection and Oscillations in Inclined Magnetic Field Regions
I. N. Kitiashvili, A. G. Kosovichev, N. N. Mansour +1
The sunspot penumbra is a transition zone between the strong vertical magnetic field area (sunspot umbra) and the quiet Sun. The penumbra has a fine filamentary structure that is c…
Excitation of acoustic waves by vortices in the quiet Sun
I. N. Kitiashvili, A. G. Kosovichev, N. N. Mansour +1
Five-minutes oscillations is one of the basic properties of solar convection. Observations show mixture of a large number of acoustic wave fronts propagating from their sources. We…
Mechanism of spontaneous formation of stable magnetic structures on the Sun
I. N. Kitiashvili, A. G. Kosovichev, A. A. Wray +1
One of the puzzling features of solar magnetism is formation of long-living compact magnetic structures; such as sunspots and pores, in the highly turbulent upper layer of the sola…
Signatures of Emerging Subsurface Structures in Acoustic Power Maps
Thomas Hartlep, Alexander G. Kosovichev, Junwei Zhao +1
We show that under certain conditions, subsurface structures in the solar interior can alter the average acoustic power observed at the photosphere above them. By using numerical s…
Explanation of the sea-serpent magnetic structure of sunspot penumbrae
I. N. Kitiashvili, L. R. Bellot Rubio, A. G. Kosovichev +3
Recent spectro-polarimetric observations of a sunspot showed the formation of bipolar magnetic patches in the mid penumbra and their propagation toward the outer penumbral boundary…
