Publication Top Notes

1. Dromion in space and laboratory dusty plasma

  • Authors: K. Annou, R. Annou

  • Journal: Physics of Plasmas, Volume 19, Article 043705 (2012)

  • Citations: 22

  • Summary:
    This paper studies dromions, which are localized two-dimensional (2D) structures, in dusty plasmas—both in space environments and laboratory settings. The authors derive conditions under which dromions can form using a two-dimensional generalization of plasma wave equations. They explore how dust grain parameters and plasma characteristics affect the generation and stability of these structures, offering insights for space plasmas (like in cometary tails) and controlled experiments.

2. Cairns-Gurevich equation for soliton in plasma expansion into vacuum

  • Authors: K. Annou, D. Bara, D. Bennaceur-Doumaz

  • Journal: Journal of Plasma Physics, Volume 81, Issue 3, Article 905810318 (2015)

  • Citations: 20

  • Summary:
    This paper derives a modified nonlinear evolution equation—specifically the Cairns-Gurevich equation—to describe the formation and propagation of solitons during plasma expansion into a vacuum. The model accounts for the nonlinearity and dispersion specific to expanding plasmas, which is important for laser-plasma interactions, astrophysical jets, and spacecraft wake studies. The study provides analytical soliton solutions and discusses physical conditions necessary for their existence.

3. Spherical Kadomtsev–Petviashvili equation for dust acoustic waves with dust size distribution and two-charges-ions

  • Authors: K. Annou, S. Bahamida, R. Annou

  • Journal: Pramana – Journal of Physics, Volume 76, Issue 3, Pages 513–518 (2011)

  • Citations: 16

  • Summary:
    In this article, the authors extend the classical Kadomtsev–Petviashvili (KP) equation into spherical geometry to describe dust acoustic waves (DAWs) in dusty plasmas. They include realistic effects like dust size distribution and two types of ion species with different charges. The spherical KP equation derived here helps explain nonlinear wave structures observed in astrophysical dusty environments, such as planetary rings and cometary comas.

4. Ion-acoustic solitons in plasma: an application to Saturn’s magnetosphere

  • Author: K. Annou

  • Journal: Astrophysics and Space Science, Volume 357, Article 1-9 (2015)

  • Citations: 14

  • Summary:
    This study applies ion-acoustic soliton theory to the conditions of Saturn’s magnetosphere. The author models the formation of ion-acoustic solitary waves under the influence of varying plasma parameters found around Saturn, including temperature ratios and density profiles. The results are relevant for interpreting data from missions like Cassini, offering insights into how nonlinear structures affect plasma transport and particle dynamics around giant planets.

5. Effect of nonthermal ion distribution and dust temperature on nonlinear dust-acoustic solitary waves

  • Authors: K. Annou, R. Annou

  • Journal: Pramana – Journal of Physics, Volume 78, Issue 1, Pages 121–126 (2012)

  • Citations: 11

  • Summary:
    This paper analyzes how a nonthermal ion distribution (departing from Maxwellian) and finite dust temperature influence the properties of dust-acoustic solitary waves. The study shows that these factors significantly modify the amplitude and width of solitary waves, affecting their stability and propagation. These findings are important for understanding nonlinear wave behavior in both laboratory dusty plasmas and cosmic settings like interstellar clouds.
