A Case Study of Nonresonant Mode 3-s ULF Waves Observed by MMS

Wang, Shan; Chen, Li-Jen; Ng, Jonathan; Bessho, Naoki; Le, Guan; Fung, Shing F.; Gershman, Daniel J.; Giles, Barbara L. (American Geophysical Union, 2020-11-16)

The nature of the 3-s ultralow frequency (ULF) wave in the Earth's foreshock region and the associated wave-particle interaction are not yet well understood. We investigate the 3-s ULF waves using Magnetospheric Multiscale ...

Solitary Magnetic Structures at Quasi-Parallel Collisionless Shocks: Formation

Chen, Li-Jen; Wang, Shan; Ng, Jonathan; Bessho, Naoki; Tang, Jian-Ming; Fung, Shing F.; Le, Guan; Gershman, Daniel; Giles, Barbara; Russell, Christopher T.; Torbert, Roy; Burch, James (American Geophysical Union, 2020-12-11)

Abstract Solitary magnetic structures known as SLAMS (short large-amplitude magnetic structures) have been considered as essential elements of collisionless shocks with quasi-parallel geometries. Yet the physics underlying ...

Magnetopause Reconnection and Indents Induced by Foreshock Turbulence

Chen, Li-Jen; Ng, Jonathan; Omelchenko, Yuri; Wang, Shan (American Geophysical Union, 2021-05-31)

Abstract Based on global hybrid simulation results, we predict that foreshock turbulence can reach the magnetopause and lead to reconnection as well as Earth-sized indents. Both the interplanetary magnetic field (IMF) and ...

Ion-scale Current Structures in Short Large-amplitude Magnetic Structures

Wang, Shan; Chen, Li-Jen; Bessho, Naoki; Hesse, Michael; Wilson III, Lynn B.; Denton, Richard; Ng, Jonathan; Giles, Barbara; Torbert, Roy; Burch, James (IOP Publishing, 2020-07-30)

We investigate electric current structures in Short Large-Amplitude Magnetic Structures (SLAMS) in the terrestrial ion foreshock region observed by the Magnetospheric Multiscale mission. The structures with intense ...
