Traveling Waves of Magnetoconvection and the Origin of the Evershed Effect in Sunspots
Irina N. Kitiashvili, Alexander G. Kosovichev, Alan A. Wray +1
Discovered in 1909 the Evershed effect represents strong mass outflows in sunspot penumbra, where the magnetic field of sunspots is filamentary and almost horizontal. These flows p…
Realistic Numerical Modeling of Solar Magnetoconvection and Oscillations
Irina Kitiashvili, Laetitia Jacoutot, Alexander Kosovichev +2
We have developed 3D, compressible, non-linear radiative MHD simulations to study the influence of the magnetic field of various strength and geometry on the turbulent convective c…
Prediction of Sunspot Cycles by Data Assimilation Method
I. N. Kitiashvili, A. G. Kosovichev
Despite the known general properties of the solar cycles, a reliable forecast of the 11-year sunspot number variations is still a problem. The difficulties are caused by the appare…
Nonlinear Solar Dynamo Model with Magnetic Helicity
I. N. Kitiashvili, A. G. Kosovichev
Variations of the sunspot number are important indicators of the solar activity cycles. The sunspot formation is a result of a dynamo process inside the Sun, which is far from bein…
