Abstract The inner magnetosphere including the radiation belt environment is replete with quasi-electrostatic fluctuations with peak frequency in the upper-hybrid frequency range. Some examples are demonstrated with the Van Allen Probe spacecraft data. These features have recently been explained in the framework of spontaneously emitted thermal noise theory. Such an environment is also characterized by quasi-isotropic population of energized electrons, which naturally leads one to ask whether these electrons and the upper-hy ...

Quasi Thermal Noise Spectroscopy for Van Allen Probes Quasi thermal fluctuations in the Langmuir/upper-hybrid frequency range are pervasively observed in space plasmas including the radiation belt and the ring current region of inner magnetosphere as well as the solar wind. The quasi thermal noise spectroscopy may be employed in order to determine the electron density and temperature as well as to diagnose the properties of energetic electrons when direct measurements are not available. However, when employing the technique, one must carefully take the spacecraft orientation in ...

High-frequency thermal fluctuations and instabilities in the radiation belt environment This paper overviews the electrostatic and electromagnetic theories of spontaneous emission in magnetized plasma as they relate to measured electric and magnetic field fluctuations in quiet time radiation belt and ring current region. The pervasively detected high-frequency fluctuations in the upper-hybrid frequency range as well as the background low-frequency range spectral profile in the whistler mode range are explained within the context of the spontaneous emission theory. The quasilinear calculation of loss-cone instab ...

Roles of hot electrons in generating upper-hybrid waves in the earth\textquoterights radiation belt Electrostatic fluctuations near upper-hybrid frequency, which are sometimes accompanied by multiple-harmonic electron cyclotron frequency bands above and below the upper-hybrid frequency, are common occurrences in the Earth\textquoterights radiation belt, as revealed through the twin Van Allen Probe spacecrafts. It is customary to use the upper-hybrid emissions for estimating the background electron density, which in turn can be used to determine the plasmapause locations, but the role of hot electrons in generating such flu ...
