Mamun Física, Astronomía y Matemáticas Dust acoustic waves Maxwellian ions Burgers equation Nonextensive electrons The nonlinear dynamics of the dust-acoustic shock waves in a dusty plasma containing negatively charged mobile dust, nonextensive electrons with two dis- tinct temperatures, and Maxwellian ions have been investi- gated by deriving the Burgers equation. The normal mode analysis is used to examine the linear properties of dust- acoustic (DA) waves. It has been observed that the proper- ties of the DA shock waves (SHWs) are significantly modi- fied by nonextensivity of the electrons, electron temperature ratios, and the respective number densities of two species of electrons. A critical value of nonextensivity is found for which shock structures transit from positive to nega- tive potential. The shock waves with positive and negative potential are obtained depending on the plasma parameters. The entailments of our results may be useful to understand the structures and the characteristics of DASHWs both in laboratory and astrophysical plasma systems. 2015 artículo científico 0103-9733 https://www.redalyc.org/articulo.oa?id=46433753013 en http://www.redalyc.org/revista.oa?id=464 Brazilian Journal of Physics application/pdf Sociedade Brasileira de Física Brazilian Journal of Physics (Brasil) Num.1 Vol.45 |
