      Duling, StefanORCIDiD; Saur, JoachimORCIDiD; Clark, GeorgeORCIDiD; Allegrini, Frederic; Greathouse, Thomas; Gladstone, RandyORCIDiD; Kurth, WilliamORCIDiD; Connerney, John E. P.ORCIDiD; Bagenal, FranORCIDiD; Sulaiman, Ali H.ORCIDiD (Geophysical Research Letters, 2022-12-20)
      Abstract

      On 7 June 2021 the Juno spacecraft visited Ganymede and provided the first in situ ...

    • Induced Magnetic Fields and Plasma Motions in the Inner Part of the Martian Magnetosphere 

      Dubinin, E.ORCIDiD; Fraenz, M.ORCIDiD; Modolo, R.ORCIDiD; Pätzold, M.ORCIDiD; Tellmann, S.; Vaisberg, O.ORCIDiD; Shuvalov, S.ORCIDiD; Zelenyi, L.ORCIDiD; Chai, L.ORCIDiD; Wei, Y.ORCIDiD; McFadden, J.; DiBraccio, G.ORCIDiD; Espley, J. (Journal of Geophysical Research: Space Physics, 2021-12-27)
      Analysis of Mars Atmosphere and Volatile Evolution (MAVEN)/Supra‐Thermal And Thermal Ion Composition observations in the Martian upper atmosphere, bounded at higher altitudes by the shocked solar wind, shows that the draping ...
    • Influence of Mercury's Exosphere on the Structure of the Magnetosphere 

      Exner, WilliORCIDiD; Simon, SvenORCIDiD; Heyner, DanielORCIDiD; Motschmann, UweORCIDiD (Journal of Geophysical Research: Space Physics, 2020)
      Mercury is embedded in a tenuous and highly anisotropic sodium exosphere, generated mainly by plasma-surface interactions. The absolute values of the sodium ion density are still under debate. Observations by MESSENGER's ...
    • Medium Energy Electron Flux in Earth's Outer Radiation Belt (MERLIN): A Machine Learning Model 

      Smirnov, A. G.ORCIDiD; Berrendorf, M.ORCIDiD; Shprits, Y. Y.ORCIDiD; Kronberg, E. A.ORCIDiD; Allison, H. J.ORCIDiD; Aseev, N. A.ORCIDiD; Zhelavskaya, I. S.ORCIDiD; Morley, S. K.ORCIDiD; Reeves, G. D.ORCIDiD; Carver, M. R.ORCIDiD; Effenberger, F.ORCIDiD (Space Weather, 2020-10-30)
      The radiation belts of the Earth, filled with energetic electrons, comprise complex and dynamic systems that pose a significant threat to satellite operation. While various models of electron flux both for low and relativistic ...
    • Results of the Electron Drift Instrument on Cluster 

      Paschmann, G.ORCIDiD; Quinn, J. M.; Torbert, R. B.ORCIDiD; McIlwain, C. E.; Vaith, H.; Haaland, S.ORCIDiD; Matsui, H.ORCIDiD; Kletzing, C. A.ORCIDiD; Baumjohann, W.ORCIDiD; Haerendel, G.ORCIDiD (Journal of Geophysical Research: Space Physics, 2021-06-23)
      The electron drift instrument (EDI) on Cluster pioneered a new method of measuring electric fields, using a beam of electrons to sample the drift velocity over a km‐scale gyro orbit. The technique is especially well suited ...
