Special Seminar: Numerical modeling of magnetic reconnection in space

Dr. Seiji Zenitani (RCUSS, Kobe University) will talk about numerical investigations on magnetic reconnection in space and solar plasmas.

Phenomena like solar flares and auroras are direct/indirect consequences of magnetic reconnection in space.  These "magnetic reconnection" events abruptly release the magnetic energy, as they change the topology of the magnetic field lines. Owning to its fundamental importance, the physics of magnetic reconnection has long been studied, by means of plasma theories, numerical simulations, and spacecraft observations.

In this talk, I will introduce some of our numerical investigations on magnetic reconnection in space and solar plasmas. By using particle-in-cell (PIC) simulations, we explore the spatial structure of a reconnection region, which helps us to understand satellite observations in near-Earth space. By using magnetohydrodynamic (MHD) simulations, we study turbulent evolution of plasmoid-dominated reconnection in a large space, such as in a solar corona. Our code, OpenMHD-GPU, is publicly available.
