MHD simulations of coronal supra-arcade downflows including anisotropic thermal conduction

, 2016
Coronal supra-arcade downflows (SADs) are observed as dark trails descending towards hot turbulent fan shaped regions. Due to the large temperature values, and gradients in these fan regions the thermal conduction should be very efficient.
