“…Recently, a number of authors have studied the nonlinear propagation of the IA waves in EPI plasmas either considering non-degenerate plasma [14][15][16][17][18][19] or degenerate plasmas. [13,[20][21][22][23][24][25] In a degenerate dense plasma, Mamun and Shukla [13] studied the SWs, and implied their results in white dwarfs.…”

A theoretical investigation has been carried out on the propagation of the ion-acoustic (IA) waves in a relativistic degenerate plasma containing relativistic degenerate electron and positron fluids in the presence of inertial non-relativistic light ion fluid. The Korteweg-de Vries (K-dV), modified K-dV (mK-dV), and mixed mK-dV (mmK-dV) equations are derived by adopting the reductive perturbation method. In order to analyze the basic features (phase speed, amplitude, width, etc.) of the IA solitary waves (SWs), the SWs solutions of the K-dV, mK-dV, and mmK-dV are numerically analyzed. It is found that the degenerate pressure, inclusion of the new phenomena like the Fermi temperatures and quantum mechanical effects (arising due to the quantum diffraction) of both electrons and positrons, number densities, etc., of the plasma species remarkably change the basic characteristics of the IA SWs which are found to be formed either with positive or negative potential. The implication of our results in explaining different nonlinear phenomena in astrophysical compact objects, e.g., white dwarfs, neutron stars, etc., and laboratory plasmas like intense laser-solid matter interaction experiments, etc., are mentioned.

“…Thus negative, ion plasma is inevitable for our consideration. This negative ion together with positive ion, positron with two-temperature and single temperature isothermal electron plasma have been studied theoretically and experimentally by many authors [1][2][3][4][5][6][7][8][9][10][11][12] for the propagation of ion-acoustic solitary waves. After showing the characteristics of solitary waves in the plasmas, they have reviewed the behaviour of the solitons in various types of plasma models making a close relationship between theoretical and experimental results.…”

In single and two-temperature non-isothermal electron plasma along with warm positive ion, warm negative ion and warm positron, propagation of non-linear ion-acoustic solitary waves are investigated under the variation of different plasma parameters. In this paper, we have studied the first, second and third order compressive non-linear solitary wave solutions along with their respective amplitudes by a very familiar approach known as 'tanh -method' with existence condition for solitary wave solutions. Again we are trying to compare the amplitudes between isothermal and non-isothermal two-temperature electron plasma. In addition to this, for two-temperature non-isothermal electron plasma -variation of energy connected with those amplitudes, fast and slow ion-accoustic phase velocity and profiles of Sagdeev potential for temperature variation of positive and negative ions are critically discussed. All the results obtained are represented graphically.

“…Thus, it is important to study the behavior of linear and nonlinear waves in e-p-i plasmas. During the past few decades, the research works on linear as well as nonlinear wave propagation in e-p-i plasmas have attracted a considerable interest from many authors [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17], because they have great importance to understand the behavior of astrophysical plasmas viz. cluster explosions, pulsar environments, supernovas, and active galactic nuclei [10,18,19].…”
