Bifurcated Current Sheet Observed on the Boundary of Kelvin-Helmholtz Vortices
Hwang, K.-J.; Dokgo, K.; Choi, E.; Burch, J.L.; Sibeck, D.G.; Giles, B.L.; Norgren, Astrid Elisabet Cecilia; Nakamura, T.K.M.; Graham, D.B.; Khotyaintsev, Y.; Shi, Q.Q.; Gershman, D.J.; Pollock, C.J.; Ergun, R.E.; Torbert, R.B.; Russell, C.T.; Strangeway, R.J. (Journal article; Peer reviewed, 2021)On May 5, 2017 MMS observed a bifurcated current sheet at the boundary of Kelvin-Helmholtz vortices (KHVs) developed on the dawnside tailward magnetopause. We use the event to enhance our understanding of the formation and ... -
Direct observations of anomalous resistivity and diffusion in collisionless plasma
Graham, D.B.; Khotyaintsev, Yu. V.; André, M.; Vaivads, A.; Divin, A.; Drake, J.F.; Norgren, Astrid Elisabet Cecilia; Le Contel, Contel; Lindqvist, P.-A.; Rager, A.C.; Gershman, D.J.; Russell, C.T.; Burch, J.L.; Hwang, K.-J.; Dokgo, K. (Journal article; Peer reviewed, 2022)Coulomb collisions provide plasma resistivity and diffusion but in many low-density astrophysical plasmas such collisions between particles are extremely rare. Scattering of particles by electromagnetic waves can lower the ...
