  1. 352. How to find magnetic nulls and reconstruct field topology with MMS data?
    Dr Huishan Fu (Beihang University)

    Workshop, August 10-14
    Invited
    In this study, we apply a new method—the first-order Taylor expansion (FOTE)—to find magnetic nulls and reconstruct magnetic field topology, in order to use it with the data from the forth-coming MMS mission. We compare this method with the previously used Poincare index (PI), and find that they are generally consistent, except that the PI method can only find a null inside the...

    Regions with vanishing magnetic field, also referred to as magnetic nulls, are of high interest in plasma physics. Near magnetic nulls particles become unmagnetized and can by interacting with electric fields be accelerated up to high energies. Magnetic nulls have been observed and studied before using in-situ observations for selected events. Here we present the first...

  3. 353. Magnetic null points in the three-dimensional kinetic simulations of space plasma
    Dr Vyacheslav Olshevsky (KU Leuven)

    Workshop, August 10-14
    Invited
    Fully kinetic electromagnetic particle-in-cell code iPic3D is used to model magnetic reconnection in the variety of plasma configurations. We apply Poincare index technique to locate and identify the topological characteristics of the magnetic null points in different three- dimensional simulations. The relevance of magnetic nulls to energy dissipation, turbulence and plasma...
