    • Faraday rotation fluctuations of MESSENGER radio signals through the equatorial lower corona near solar minimum 

      Wexler, D.B.; Jensen, E.A.; Hollweg, J.V.; Heiles, C.; Efimov, A.I.; Vierinen, J.; Coster, A.J. (Journal article; Peer reviewed; Tidsskriftsartikkel, 2016-12-26)
      Faraday rotation (FR) of transcoronal radio transmissions from spacecraft near superior conjunction enables study of the temporal variations in coronal plasma density, velocity, and magnetic field. The MESSENGER spacecraft 8.4 GHz radio, transmitting through the corona with closest line-of-sight approach 1.63–1.89 solar radii and near-equatorial heliolatitudes, was recorded soon after the deep ...
