Convection and the origin of Evershed flows in sunspot penumbrae
G. B. Scharmer, A. Nordlund, T. Heinemann
We discuss a numerical 3D radiation-MHD simulation of penumbral fine structure in a small sunspot. This simulation shows the development of short filamentary structures with horizo…

MHD simulations of penumbra fine structure
T. Heinemann, A. Nordlund, G. B. Scharmer +1
We present results of numerical 3D MHD simulations with radiative energy transfer of fine structure in a small sunspot of about 4 Mm width. The simulations show the development of…

Magnetostatic penumbra models with field-free gaps
G. B. Scharmer, H. C. Spruit
We present numerical 2D magnetostatic models for sunspot penumbrae consisting of radially aligned field-free gaps in a potential magnetic field, as proposed by Spruit and Scharmer…
