Abstract Space plasmas present intriguing and challenging puzzles to the space community.
Energy accessible to excite instabilities exists in a variety of forms, particularly for the …

Occurrence of electrostatic solitary waves (ESWs) is ubiquitous in space plasmas, eg, solar
wind, Lunar wake and the planetary magnetospheres. Several theoretical models have …

Cosmic plasmas are considered as the most abundant form of ordinary matter in the
Universe while observations of the cosmic dust in different regions provide an insight into …

Generation of electron-acoustic waves (EAWs) is examined in an unmagnetized, four-
component plasma consisting of stationary cold and hot Maxwellian electrons, drifting …

We present two cases of abrupt dayside auroral brightenings and very fast auroral
propagation using the POLAR UV imaging data. The brightenings occur first at noon and …

Small‐scale solitary electric potential structures are commonly observed on auroral field
lines with the Polar Electric Field Instrument (EFI). This study focuses on observations of …

Properties of ion-and electron-acoustic solitons are investigated in an unmagnetized
multicomponent plasma system consisting of cold and hot electrons and hot ions using the …

Electron-acoustic solitary waves are studied in an unmagnetized plasma consisting of non-
thermally distributed electrons, fluid cold electrons and ions. The Sagdeev pseudo-potential …

When a Coronal Mass Ejection struck the Earth on January 10, 1997, Electrostatic Solitary
Waves (ESW) and Amplitude Modulated Electrostatic Waves (AMEW) were detected as …

Global signatures of the aurora caused by interplanetary shocks/pressure pulses have been
studied in recent years using ultraviolet imager data from polar orbiting spacecraft. The …
