    • Spacecraft Radio Frequency Fluctuations in the Solar Corona: A MESSENGER–HELIOS Composite Study 

      Wexler, David; Hollweg, J. V.; Efimov, A. I.; Lukanina, L. A.; Coster, Anthea; Vierinen, Juha; Jensen, E. A. (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-01-31)
      Fluctuations in plasma electron density may play a role in solar coronal energy transport and the dissipation of wave energy. Transcoronal spacecraft radio sounding observations reveal frequency fluctuations (FFs) that encode the electron number density disturbances, allowing an exploration of the coronal compressive wave and advected inhomogeneity models. Primary FF observations from MESSENGER 2009 ...
