    • High‐density magnetospheric He+ at the dayside magnetopause and its effect on magnetic reconnection 

      Fuselier, Stephen A.; Haaland, Stein; Tenfjord, Paul; Paschmann, G; Toledo-Redondo, S; Malaspina, D; Kim, M.J.; Trattner, K.J.; Petrinec, S. M.; Giles, B. L.; Goldstein, J; Burch, J. L.; Strangeway, R. J. (Journal article; Peer reviewed, 2021)
      Observations from the Magnetospheric Multiscale (MMS) mission are used to quantify the maximum effect of magnetospheric H+ and He+ on dayside magnetopause reconnection. A data base of current-sheet crossings from the first ...

    • High‐density O+ in Earth's outer magnetosphere and its effect on dayside magnetopause magnetic reconnection 

      Fuselier, SA; Mukherjee, J; Denton, MH; Petrinec, SM; Trattner, K.J.; Toledo-Redondo, S; Andre, M; Aunai, N; Chappell, Charles Richard; Glocer, Alex; Haaland, S.; Hesse, Michael; Kistler, LM; Lavraud, B; Li, WY; Moore, T. E.; Graham, D; Tenfjord, Paul; Dargent, J.; Vines, Sarah K.; Strangeway, Robert J.; Burch, J. L. (Journal article; Peer reviewed, 2019)
      The warm plasma cloak is a source of magnetospheric plasma that contain significant O+. When the O+ density in the magnetosphere near the magnetopause is >0.2 cm‐3 and the H+ density is <1.5 cm‐3, then O+ dominates the ...

    • Kelvin-Helmholtz Instability Associated With Reconnection and Ultra Low Frequency Waves at the Ground: A Case Study 

      Kronberg, E.A.; Gorman, J.; Nykyri, K.; Smirnov, Artem; Gjerløv, Jesper; Grigorenko, Elena; Kozak, L.V.; Ma, Xuanye; Trattner, K.J.; Friel, M. (Journal article; Peer reviewed, 2021)
      The Kelvin-Helmholtz instability (KHI) and its effects relating to the transfer of energy and mass from the solar wind into the magnetosphere remain an important focus of magnetospheric physics. One such effect is the ...

    • Mass‐loading the Earth's dayside magnetopause boundary layer and its effect on magnetic reconnection 

      Fuselier, Stephen; Trattner, K.J.; Petrinec, Steve M.; Denton, Mike; Toledo, Sergio P.A.; Andrè, M.; Aunai, N; Chappell, Charles Richard; Glocer, Alex; Haaland, Stein; Hesse, Michael; Kistler, Lynn M.; Li, Wenya; Moore, T. E.; Graham, Daniel B.; Alm, Love; Tenfjord, Paul; Dargen, Jeremy; Vines, Sarah; Nykyri, K.; Burch, James L; Strangeway, Robert J. (Peer reviewed; Journal article, 2019)
      When the interplanetary magnetic field is northward for a period of time, O+ from the high‐latitude ionosphere escapes along reconnected magnetic field lines into the dayside magnetopause boundary layer. Dual‐lobe reconnection ...
