Generation of mean flows in rotating anisotropic turbulence: The case of solar near-surface shear layer
A. Barekat, M. J. Käpylä, P. J. Käpylä +2
The radial gradient of the rotation rate in the near-surface shear layer (NSSL) of the Sun is independent of latitude and radius. Theoretical mean-field models have been successful…
Solar-cycle variation of the rotational shear near the solar surface
Atefeh Barekat, Jesper Schou, Laurent Gizon
Helioseismology has revealed that the angular velocity of the Sun increases with depth in the outermost 35 Mm of the Sun. Recently, we have shown that the logarithmic radial gradie…
The radial gradient of the near-surface shear layer of the Sun
Atefeh Barekat, Jesper Schou, Laurent Gizon
Helioseismology has provided unprecedented information about the internal rotation of the Sun. One of the important achievements was the discovery of two radial shear layers: one n…
Near-polytropic simulations with a radiative surface
Atefeh Barekat, Axel Brandenburg
Studies of solar and stellar convection often employ simple polytropic setups using the diffusion approximation instead of solving the proper radiative transfer equation. This allo…
