    • Electron inflow velocities and reconnection rates at earth's magnetopause and magnetosheath 

      Burch, James L.; Webster, James M.; Hesse, Michael; Genestreti, Kevin J.; Denton, Richard E.; Phan, Tai D.; Hasegawa, Hiroshi; Cassak, Paul A.; Torbert, Roy B.; Giles, Barbara L.; Gershman, Daniel J.; Ergun, Robert E.; Russell, Christopher T.; Strangeway, Robert J.; Le Contel, Olivier; Pritchard, Kris R.; Marshall, Andrew T.; Hwang, Kyoung-Joo; Dokgo, Kyunghwan; Fuselier, Stephen A.; Chen, Li-Jen; Wang, Shan; Swisdak, Marc; Drake, James F.; Argall, Matthew R.; Trattner, Karlheinz J.; Yamada, Masaaki; Paschmann, Götz (Journal article; Peer reviewed, 2020)
      Electron inflow and outflow velocities during magnetic reconnection at and near the dayside magnetopause are measured using satellites from NASA's Magnetospheric Multiscale (MMS) mission. A case study is examined in detail, ...

    • Ion Behaviors in the Reconnection Diffusion Region of a Corrugated Magnetotail Current Sheet 

      Wang, Shan; Chen, Li-Jen; Bessho, Naoki; Hesse, Michael; Giles, Barbara L; Moore, Thomas E (Journal article; Peer reviewed, 2019)
      The current sheet structure and ion behaviors in a magnetotail reconnection diffusion region are investigated. The multispacecraft analysis suggests a corrugated current sheet structure, interpreted as due to a flapping ...

    • Lower-Hybrid Drift Waves Driving Electron Nongyrotropic Heating and Vortical Flows in a Magnetic Reconnection Layer 

      Chen, Li-Jen; Wang, Shan; Le Contel, Olivier; Rager, A.; Hesse, Michael; Drake, J. F.; Dorelli, J.; Ng, J.; Bessho, Naoki; Graham, D. B.; Wilson, Lynn B.; Moore, T. E.; Giles, B. L.; Paterson, W.; Lavraud, B.; Genestreti, K.; Nakamura, Rumi; Khotyaintsev, Yuri V.; Ergun, R.E.; Torbert, Roy B.; Burch, J. L.; Pollock, C.; Russell, Christopher T.; Lindqvist, Per-Arne; Avanov, Levon (Journal article; Peer reviewed, 2020)
      We report measurements of lower-hybrid drift waves driving electron heating and vortical flows in an electron-scale reconnection layer under a guide field. Electrons accelerated by the electrostatic potential of the waves ...

    • Magnetospheric Multiscale Observations of an Expanding Oxygen Wave in Magnetic Reconnection 

      Kolstø, Håkon Midthun; Norgren, Astrid Elisabet Cecilia; Hesse, Michael; Chen, Li-Jen; Tenfjord, Paul; Spinnangr, Susanne Flø; Kwagala, Norah Kaggwa (Journal article; Peer reviewed, 2021)
      Heavier plasma species such as oxygen ions can have a large impact on the magnetic reconnection process. It has been hypothesized that the acceleration of demagnetized oxygen ions by the Hall electric field will lead to ...

    • Observational Evidence of Magnetic Reconnection in the Terrestrial Bow Shock Transition Region 

      Wang, Shan; Chen, Li-Jen; Bessho, Naoki; Hesse, Michael; Wilson, Lynn B.; Giles, Barbara; Moore, Thomas E.; Russell, Christopher T.; Torbert, Roy B.; Burch, James L. (Journal article; Peer reviewed, 2019)
      We report evidence of magnetic reconnection in the transition region of the Earth's bow shock when the angle between the shock normal and the immediate upstream magnetic field is 65°. An ion‐skin‐depth‐scale current sheet ...
