Current concentrations in the solar corona — •Jörg Büchner — Max-Planck-Institut für Sonnensystemforschung

The heating of the solar corona and solar eruptions are due to energy flows from the photosphere. here magnetic coupling plays a crucial role. One of the possible mediators of this energy are currents. Since coronal currents are invisible one has to derive their location, structure and strength from the most reliable information available - the photospheric magnetic fields and plasma flows. We demonstrate the results of such approach and compare them with observation of the consequences of current concentrations like localized heating events and eruptions in the solar atmosphere.
