Helioseismic Fréchet Traveltime Kernels in Spherical Coordinates
R. B. Schlottmann, A. G. Kosovichev
Seismic traveltime measurements are a crucial tool in the investigation of the solar interior, particularly in the examination of fine-scale structure. Traditional analysis of trav…
First Sunquake of Solar Cycle 24 Observed by Solar Dynamics Observatory
A. G. Kosovichev
The X2.2-class solar flare of February 15, 2011, produced a powerful `sunquake' event, representing a seismic response to the flare impact. The impulsively excited seismic waves fo…
Analysis of SOHO/MDI and TRACE Observations of Sunspot Torsional Oscillation in AR10421
O. S. Gopasyuk, A. G. Kosovichev
Rotation of the leading sunspot of active region NOAA 10421 was investigated using magnetograms and Dopplergrams from the MDI instrument of the Solar and Heliospheric Observatory (…
LES of turbulent convection in solar-type stars and formation of large-scale magnetic structures
I. Rogachevskii, N. Kleeorin, I. N. Kitiashvili +3
In this study we investigate the effects of turbulent convection on formation of large-scale inhomogeneous magnetic structures by means of Large-Eddy Simulation (LES) for convectio…
Turbulent 3D MHD dynamo model in spherical shells: Regular oscillations of the dipolar field
R. D. Simitev, F. H. Busse, A. G. Kosovichev
We report the results of three-dimensional numerical simulations of convection-driven dynamos in relatively thin rotating spherical shells that show a transition from an strong non…
