Spectrum of kinetic plasma turbulence at 0.3-0.9 astronomical units from the Sun

Olga Alexandrova, Vamsee Krishna Jagarlamudi, Petr Hellinger +3

We investigate spectral properties of turbulence in the solar wind that is a weakly collisional astrophysical plasma, accessible to in-situ observations. Using the Helios search co…

On a transitional regime of electron resonant interaction with whistler-mode waves in inhomogeneous space plasma

A. V. Artemyev, A. I. Neishtadt, A. A. Vasiliev +1

Resonances with electromagnetic whistler-mode waves are the primary driver for the formation and dynamics of energetic electron fluxes in various space plasma systems, including sh…
