A simple analytic model of reconnection in a high-temperature turbulent sheet

We present a simple model of high-temperature (T greater than or equal to 1 0(8) K) turbulent current sheets forming in magnetic-reconnection regions o n the Sun. The model is based on an empirical formula by de Kluiver er nl. (1991) for turbulent plasma conductivity and is apparently valid over a wid e range of physical conditions. A comparison of the new results with known test calculations suggests agreement between the theoretical and empirical approaches to calculating the anomalous conductivity in turbulent plasma. T he energy release in current sheets is powerful enough for flares, coronal transients, and coronal mass ejections to be interpreted. (C) 2000 MAIK "Na uka/Interperiodica".
