The problem of small and large scale fields in the solar dynamo
A. Brandenburg, N. E. L. Haugen, P. J. Käpylä +1
Three closely related stumbling blocks of solar mean field dynamo theory are discussed: how dominant are the small scale fields, how is the alpha effect quenched, and whether magne…
Helical coronal ejections and their role in the solar cycle
Axel Brandenburg, Christer Sandin, Petri J. Käpylä
The standard theory of the solar cycle in terms of an alpha-Omega dynamo hinges on a proper understanding of the nonlinear alpha effect. Boundary conditions play a surprisingly imp…
Catastrophic alpha quenching alleviated by helicity flux and shear
Axel Brandenburg, Christer Sandin
A new simulation set-up is proposed for studying mean field dynamo action. The model combines the computational advantages of local cartesian geometry with the ability to include a…
Three-component modeling of C-rich AGB star winds III. Micro-physics of drift-dependent dust formation
C. Sandin, S. Hoefner
A proper treatment of the non-equilibrium dust formation process is crucial in models of AGB star winds. In this paper the micro-physics of this process is treated in detail, with…
