Magnetic flux tubes evolving in sunspots. A model for the penumbral finestructure and the Evershed effect
R. Schlichenmaier, K. Jahn, H. U. Schmidt
Assuming that the interchange convection of magnetic flux elements is the physical cause for the existence of filamentary penumbrae in sunspots, we investigate the behavior of an i…
A dynamical model for the penumbral fine structure and the Evershed effect in sunspots
R. Schlichenmaier, K. Jahn, H. U. Schmidt
Relying on the assumption that the interchange convection of magnetic flux tubes is the physical cause for the existence of sunspot penumbrae, we propose a model in which the dynam…
Evolution of a Magnetic Flux Tube in a Sunspot Penumbra
K. Jahn, R. Schlichenmaier, H. U. Schmidt
The motion of an individual magnetic flux tube inside the penumbra of a sunspot is studied numerically. Here, we present preliminary results. The thin flux tube approximation toget…
Thick Penumbra in a Magnetostatic Sunspot Model
K. Jahn, H. U. Schmidt
The conjecture that energy transport in sunspot penumbrae occurs through convection by an interchange of magnetic flux tubes is used in order to construct a magnetostatic model for…
