Viktor Fedun (Sheffield): Vortex motions in the solar atmosphere
Abstract:
Solar photosphere vortices have the potential to form coherent magnetic field structures, e.g. twisted magnetic flux tubes and, therefore, may play a key role in the transport of energy and momentum from the lower atmosphere into the upper solar atmosphere. In this talk I will review existing methods for their identification and discuss our approach, which is based on Gamma detection and LAVD of inter-granular photospheric intensity vortices. I will also present new mechanism for the generation of magnetic waveguide from the lower solar atmosphere to the corona. This waveguide appears as the result of interacting perturbations (initially generated by photospheric vortex motions) in neighbouring magnetic flux tubes (modelled in the framework of self-similar approach).
