Astrophysics has traditionally been pursued at astronomical observatories and on theorists'
computers. Observations record images from space, and theoretical models are developed …

The nonlinear three-dimensional modified Korteweg–de Vries–Zakharov–
Kuznetsov​(mKdV–ZK) equation governs the behavior of weakly nonlinear ion-acoustic …

Dynamics of ion acoustic waves are studied in Thomas-Fermi plasmas with source term
consisting of electrons, positrons and positive ions, where electrons and positrons follow …

A quantum kinetic equation, valid for relativistic unmagnetized plasmas, is derived here. This
equation describes the evolution of a quantum quasi-distribution, which is the Wigner …

Nonlinear propagation of fast and slow magnetosonic perturbation modes in an
ultrarelativistic, ultracold, degenerate (extremely dense) electron positron (EP) plasma …

Based on the quantum hydrodynamics theory, a rigorous model for ion acoustic shock
waves (IASWs) in a degenerate relativistic plasma with heavy ion nuclei is presented. Two …

Kinetic instabilities arising from anisotropic electron velocity distributions are ubiquitous in
ionospheric, cosmic, and terrestrial plasmas, yet there are only a handful of experiments that …

Bifurcation analysis of ion-acoustic (IA) superperiodic waves is studied in dense plasmas
composed of electrons, positrons, and positive ions. Employing bifurcation analysis of …

The theoretical and numerical studies have been investigated on nonlinear propagation of
weakly relativistic ion acoustic solitary waves in an unmagnetized plasma system consisting …

Small amplitude propagation and quasielastic head-on collision of ion-acoustic solitary
waves (IASWs) are investigated in a degenerate Thomas–Fermi electron-positron-ion …
