Modulated Dust-Acoustic Wavepackets in aKappa-Distributed Nonthermal PlasmaBackground

摘要

Dust is a ubiquitous component of space and astrophysical environments occurring,for exam- ple, in planetary rings, comets, the Earth's ionosphere, interstellar molecularclouds etc. [1]. Dusty plasmas are known to support new electrostatic/electromagneticmodes, which were pre- dicted theoretically and conlvmed experimentally [2, 3].
