Radiative MHD simulation of sunspot structure
M. Rempel, M. Schuessler, M. Knoelker
Results of a 3D MHD simulation of a sunspot with a photospheric size of about 20 Mm are presented. The simulation has been carried out with the MURaM code, which includes a realist…
Origin of solar torsional oscillations
Matthias Rempel
Helioseismology has revealed many details of solar differential rotation and also its time variation, known as torsional oscillations. So far there is no generally accepted theoret…
Transport of toroidal magnetic field by the meridional flow at the base of the solar convection zone
Matthias Rempel
In this paper we discuss the transport of toroidal magnetic field by a weak meridional flow at the base of the convection zone. We utilize the differential rotation and meridional…
Influence of random fluctuations in the Lambda-effect on meridional flow and differential rotation
Matthias Rempel
We present a mean field model based on the approach taken by Rempel (astro-ph/0604451) in order to investigate the influence of stochastic fluctuations in the Reynolds stresses on…
Solar differential rotation and meridional flow: The role of a subadiabatic tachocline for the Taylor-Proudman balance
Matthias Rempel
We present a simple model for the solar differential rotation and meridional circulation based on a mean field parameterization of the Reynolds stresses that drive the differential…
Flux-transport dynamos with Lorentz force feedback on differential rotation and meridional flow: Saturation mechanism and torsional oscillations
Matthias Rempel
In this paper we discuss a dynamic flux-transport dynamo model that includes the feedback of the induced magnetic field on differential rotation and meridional flow. We consider tw…
The uncombed penumbra
J. M. Borrero, M. Rempel, S. K. Solanki
The uncombed penumbral model explains the structure of the sunspot penumbra in terms of thick magnetic fibrils embedded in a magnetic surrounding atmosphere. This model has been su…
Concentration of toroidal magnetic field in the solar tachocline by eta-quenching
Peter A. Gilman, Matthias Rempel
We show that if the turbulent magnetic diffusivity used in solar dynamos is assumed to be 'quenched' by increasing toroidal fields, much larger amplitude and more concentrated toro…
