Resumo | Previous works have demonstrated that the technique of hyperbolic Lagrangian coherent structures is useful for analyzing the dynamics of velocity and magnetic fields in numerical simulations and satellite observations of astrophysical plasmas such as solar photospheric turbulence. An accurate detection of the boundary of coherent structures in velocity and magnetic fields of a plasma is fundamental for the study of astrophysical turbulence, for example, the determination of the front and rear boundary layers of magnetic flux ropes in the solar wind is essential for locating the preferential sites for the genesis of interplanetary intermittent turbulence. In this work we apply the approach of rotational Lagrangian coherent structures to detect kinematic vortices in 3D magnetohydrodynamic simulations of an astrophysical dynamo. The objective kinematic vortices are given by tubular level surfaces of the Lagrangian Averaged Vorticity Deviation (LAVD), the trajectory integral of the normed difference of the vorticity from its spatial mean. In addition, we adapt the LAVD technique to use it on magnetic fields and propose the method of Integrated Averaged Current Deviation (IACD) to determine precisely the boundary of magnetic vortices. The relevance of objective kinematic and magnetic vortices in solar plasmas is discussed. |
