Imaging the Solar Tachocline by Time-Distance Helioseismology
Junwei Zhao, Thomas Hartlep, A. G. Kosovichev +1
The solar tachocline at the bottom of the convection zone is an important region for the dynamics of the Sun and the solar dynamo. In this region, the sound speed inferred by globa…
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…
Signatures of emerging subsurface structures in the sun
T. Hartlep, A. G. Kosovichev, J. Zhao +1
The complex dynamics that lead to the emergence of active regions on the sun are poorly understood. One possibility is that magnetic structures (flux tubes, etc.) rise from below t…
