    • 20 Years of Cluster Observations: The Magnetopause, 

      Håland, Stein Egil; Hasegawa, Hiroshi; Paschmann, G; Sonnerup, B. U. Ö.; Dunlop, M. W. (Journal article; Peer reviewed, 2021)
      The terrestrial magnetopause forms the boundary between the solar wind plasma with its embedded interplanetary magnetic field on one side, and the terrestrial magnetosphere, dominated by Earth's dipole field, on the other ...

    • Characteristics of the Flank Magnetopause: MMS Results 

      Haaland, Stein; Paschmann, Götz; Oieroset, M; Phan, Tai D.; Hasegawa, Hiroshi; Fuselier, Stephen; COnstantinescu, Vlad; Eriksson, Stefan; Trattner, Karlheinz J.; Fadanelli, Sid; Tenfjord, Paul; Lavraud, Benoit; Norgren, Astrid Elisabet Cecilia; Eastwood, Jonathan P.; Hietala, Heli; Burch, J (Journal article; Peer reviewed, 2020)
      We have used a large number of magnetopause crossings by the Magnetospheric Multiscale (MMS) mission to investigate macroscopic properties of this current sheet, with emphasis on the flanks of the magnetopause. Macroscopic ...

    • Dayside Transient Phenomena and Their Impact on the Magnetosphere and Ionosphere 

      Zhang, Hui; Zong, Qiugang; Connor, Hyunju; Delamere, Peter; Facskó, Gábor; Han, Desheng; Hasegawa, Hiroshi; Kallio, Esa; Kis, Árpád; Le, Guan; Lembège, Bertrand; Lin, Yu; Liu, Terry; Oksavik, Kjellmar; Omidi, Nojan; Otto, Antonius; Ren, Jie; Shi, Quanqi; Sibeck, David; Yao, Shutao (Journal article; Peer reviewed, 2022)
      Dayside transients, such as hot flow anomalies, foreshock bubbles, magnetosheath jets, flux transfer events, and surface waves, are frequently observed upstream from the bow shock, in the magnetosheath, and at the magnetopause. ...

    • 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, ...
