Abstract:
Vortices in the solar atmosphere present an ideal driving mechanism for Alfvenic waves that can efficiently carry energy in the upper layers of the chromosphere and corona. However, the identification and classification of vortical motions from observations and numerical simulations is a challenging task. In this work we leverage a number of methods conventionally employed in turbulence to identify for the fist time in the solar atmosphere vortices, in an automated fashion. We also present a statistical analysis of the properties of the identified motions and relate this with theoretical results for such magnetic structures.
