On the magnetic field topology in reconnection region
Abstract
Magnetic reconnection is generally accompanied by large and quasi-turbulent spatio-temporal fluctuations from the MHD scales down to the kinetic ones. The study of these turbulent fluctuations is generally based on the investigation of spectral and scaling features. In a recent paper by Consolini et al. [1] it has been shown how the statistics of geometrical invariants of coarse-grained gradient tensor of plasma velocity is able to provide valuable information on the topology of the turbulent structures. Here, we present a preliminary study of the topology of magnetic field structures at kinetic scales in the X-line/dissipation region of a reconnection event observed by MMS constellation [2]. The analysis evidenced vortex sheet Ohmic-dissipation.
