A statistical study of kinetic‐size magnetic holes in turbulent magnetosheath: MMS observations
Kinetic‐size magnetic holes (KSMHs) in the turbulent magnetosheath are statistically investigated using high time resolution data from the Magnetospheric Multiscale mission. The KSMHs with short duration (i.e.,

Plain Language Summary
A nonlinear energy cascade in magnetized turbulent plasmas leads to the formation of different coherent structures which are thought to play an important role in dissipating energy and transporting particles. This study statistically investigate one new type of coherent structure, named electron vortex magnetic hole, used by Magnetospheric Multiscale data. It reveals the common features of this structure, including an increase in the electron density and total temperature, significantly increase (resp. decrease) the electron perpendicular (resp. parallel) temperature and an electron vortex inside these holes. The increase of electron temperature inside the holes indicates that these holes are likely to heat and accelerate the electrons. This gives new clue for energy dissipation in turbulent plasmas.</description><identifier>ISSN: 2169-9380</identifier><identifier>EISSN: 2169-9402</identifier><identifier>DOI: 10.1002/2017JA024415</identifier><language>eng</language><publisher>Washington: Blackwell Publishing Ltd</publisher><subject>Astrophysics ; electron acceleration/heating ; Electron density ; Electron energy ; Electron flux ; electron vortex ; Energy dissipation ; Heat ; kinetic‐size magnetic hole ; Magnetosheath ; Magnetospheres ; mangetosheath ; Particle in cell technique ; Particle physics ; Physics ; Plasma Physics ; Plasmas (physics) ; Studies ; Turbulence ; turbulent plasma ; Vortices</subject><ispartof>Journal of geophysical research.
