Anomalous Resistivity as the Possible Cause of Fast Reconnection in the Solar Corona

This paper develops Strauss' (1988) idea of anomalous resistivity that causes a solar flare to occur. Anomalous resistivity arises due to an interaction of a multitude of current sheets resulting in an abrupt increase of resistivity of the medium. This process is considered in a distributed current system of a force-free field of the solar corona. Estimates are made of the time of development of anomalous resistivity and of the explosive phase for coronal conditions. The process is compared with the preliminary and impulsive phase of two-ribbon flares.
