Thermal instability and multiphase dynamics in the ISM with polybaric pressure effects
Hitendra Sarkar, Madhurjya P. Bora
In this work, we have carried out a two-dimensional (2D) simulation of thermal instability (TI) in interstellar matter (ISM), considering it to be a weakly ionised inviscid plasma…
External charged debris in a flowing plasma : charge fluctuation induced complexity
Bikramjit Joardar, Hitendra Sarkar, Madhurjya P. Bora
In this work, we investigate the response of a flowing e-i plasma to embedded external charged debris, focusing on the periodic debris charge fluctuations that can trigger complex…
Exploring nonlinearities in a positive ion-negative ion (PINI) plasma: can other processes mimic debris-induced effects?
Hitendra Sarkar, Madhurjya P. Bora
In this work, an analysis of nonlinear waves and structures induced by an external charged debris in a positive ion-negative ion (PINI) plasma is presented. The results obtained ar…
External charge perturbation in a flowing plasma and electrostatic turbulence
Mridusmita Das, Madhurjya P. Bora
In this work, an 1D electrostatic hybrid-Particle-in-Cell-Monte-Carlo-Collisionh-PIC-MCC) code is used to study the response of a plasma to a moving, external, charged perturbation…
Fast-moving electrostatic solitons in a plasma with turbulence heating
Mridusmita Das, Murchana Khusroo, Madhurjya P. Bora
In this work, it is shown that electrostatic solitons in a plasma with turbulent heating of the electrons through an accelerating electric field can form with very high velocities,…
