Acceleration of dust particles by vortex ring
Zahida Ehsan, N. L. Tsintsadze, J. Vranjes +4
It is shown that nonlinear interaction between large amplitude circularly polarized EM wave and dusty plasma leads to a nonstationary ponderomotive force which in turn produces a v…
Self-heating and its possible relationship to chromospheric heating in slowly rotating stars
Andria Rogava, Zaza Osmanov, Stefaan Poedts
The efficiency of nonmodal self-heating by acoustic wave perturbations is examined. Considering different kinds of kinematically complex velocity patterns we show that nonmodal ins…
Solar nanoflares and other smaller energy release events as growing drift waves
J. Vranjes, S. Poedts
Rapid energy releases (RERs) in the solar corona extend over many orders of magnitude, the largest (flares) releasing an energy of J or more. Other events, with a typical…
Electric fields in solar magnetic structures due to gradient driven instabilities: heating and acceleration of particles
J. Vranjes, S. Poedts
The electrostatic instabilities driven by the gradients of the density, temperature and magnetic field, are discussed in their application to solar magnetic structures. Strongly gr…
Weak and strong regimes of incompressible magnetohydrodynamic turbulence
G. Gogoberidze, S. M. Mahajan, S. Poedts
It is shown that in the framework of the weak turbulence theory, the autocorrelation and cascade timescales are always of the same order of magnitude. This means that, contrary to…
Kinetic instability of ion acoustic mode in permeating plasmas
J. Vranjes, S. Poedts, Z. Ehsan
In plasmas with electron drift (current) relative to static ions, the ion acoustic wave is subject to the kinetic instability which takes place if the directed electron speed excee…
