On the nature of 3D current layers in the solar atmosphere

Abstract:

Electric currents are pervasive throughout the solar atmosphere. However, when strong concentrations of currents arise, the dynamic behaviour of the magnetic field and plasma can completely change giving rise to significant releases of magnetic energy. As such understanding how and where current layers form is essential to both understanding and predicting magnetic-energy-release events.   In this talk, I will focus on the formation of three-dimensional current layers: both where and how they may form. The differences between current layers in low and high beta magnetohydrostatic equilibria will be discussed. Finally I will briefly touch on the evolution of a current layer once magnetic reconnection is initiated.
