Modelling the evolution of the Sun's open and total magnetic flux
N. A. Krivova, S. K. Solanki, B. Hofer +3
Solar activity in all its varied manifestations is driven by the magnetic field. Particularly important for many purposes are two global quantities, the Sun's total and open magnet…
Solar cyclic activity over the last millennium reconstructed from annual 14C data
I. G. Usoskin, S. K. Solanki, N. Krivova +5
The 11-year solar cycle is the dominant pattern of solar activity reflecting the oscillatory dynamo mechanism in the Sun. Solar cycles were directly observed since 1700, while indi…
Application of the electromotive force as a shock front indicator in the inner heliosphere
Bernhard Hofer, Philippe-A. Bourdin
The electromotive force (EMF) describes how the evolution and generation of a large-scale magnetic field is influenced by small-scale turbulence. Recent studies of in-situ measurem…
Inner Structure of CME Shock Fronts Revealed by the Electromotive Force and Turbulent Transport Coefficients in Helios-2 Observations
Philippe-A. Bourdin, Bernhard Hofer, Yasuhito Narita
Electromotive force is an essential quantity in dynamo theory. During a coronal mass ejection (CME), magnetic helicity gets decoupled from the Sun and advected into the heliosphere…
