How do Dipolarizing Flux Bundles Impact the cis-GEO Inner Magnetosphere



Jiang Liu 

UCLA, EPSS



ABSTRACT

Dipolarizing flux bundles (DFBs) are flux tubes in Earth’s magnetotail, which have larger Bz than the background. These bundles are most likely generated by near-earth tail reconnection. After they are generated, they propagate earthward (as bursty bulk flows) and carry strong electric fields. Their strong electric field can energize particles. If DFBs can bring these energized particles into the inner magnetosphere, they can impact the particle population of the ring current and the radiation belt. Even if a DFB cannot reach the inner magnetosphere, it may still impact the particle population there by sending ultra-low-frequency waves. In this talk, I explore the possible ways that DFBs can transport their energy to the inner magnetosphere.
