Original research contribution:
P.A. Bespalov produced important contribution to creation of the contemporary theory of collective effects and global processes in the plasmaspheres of planets and stars. The parameters of steady-state at the finite width of electromagnetic wave spectra are examined. Oscillatory processes in the particle fluxes and wave spectra are analyzed. The possibility of specific instability of the radiation belts steady-state, connected with modulation of the angular distribution function of energetic particles, is discovered. The effect of passive synchronization of modes in the plasma magnetospheric maser is discovered. The exact soliton solution with electromagnetic waves spectrum dynamic is found. The theory of quasi-periodic VLF emissions, wave of precipitations into the ionosphere, and short-period electromagnetic emissions is proposed.
Significant attention is given to study of the plasma magnetospheric maser in the radiation belts of Jupiter. The effect of global resonance is proposed and substantiated. The reason for the excitation of chorus emissions in three spectral bands is explained. The three-dimensional temporary dynamic of cyclotron interaction of energetic electrons with electromagnetic wave in the nonuniform magnetic field is studied. Dynamic and stochastic acceleration of the epithermal charge particle fluxes in the high-latitude regions of the Earth and Jupiter magnetosphere are examined.
Should be noted the papers, dedicated to the study of processes in the star and planetary plasma envelope. The problem of disk formation in the stellar envelope as a result of the high radiation pressure is examined. The properties of plasma disk in the magnetosphere of Jupiter are analyzed. An approach to study of the nonstationary current systems, which appear after magnetic storms, is developed. The model of planetary electric generator, which modify known ideas about nature of atmospheric electricity and electrodynamics of the rotating star and planetary plasma envelope, is examined.
Significant progress is achieved during the study of collective processes in the Solar atmosphere. The multivariate quasi-linear relaxation of electronic fluxes in the Solar corona is analyzed. The reason for different time scales of energetic proton and electron fluxes dispersion during the explosive processes with the high level of plasma turbulence in the coronal arches is explained. The special features of transfer and resonant amplification of hydromagnetic waves in the two-dimensional not uniform Solar wind are examined. The generalized Wiedemann–Franz law for the non-isothermic quasi-neutral plasma with developed ion-acoustic turbulence is proved. This law determines the relationship between electrical and thermal conductivities in plasma with well-developed ion-acoustic turbulence. The anomalously low thermal conductivity, which leads to the formation of high temperature gradients, is explained. These results are used to explain some properties of the Solar chromosphere – corona transition region.
