Mamun Física, Astronomía y Matemáticas Two ion Dust acoustic waves Kappa distribution The basic properties of nonplanar (viz. cylindri- cal and spherical) dust-ion-acoustic (DIA) shock waves in an unmagnetized dusty plasma system [consisting of inertial ions, negatively charged immobile dust, and superthermal electrons with two distinct temperatures] are investigated by employing the reductive perturbation method. The modified Burgers equation is derived an d is numerically analyzed in order to examine the basic properties of DIA shock struc- tures. The effects of nonplanar geometry, electron superther- mality, and ion kinematic viscosity on the basic features of DIA shock waves are discussed. It is found that the prop- erties of the cylindrical and spherical DIA shock waves in dusty plasmas with two-temperature superthermal elec- trons significantly differ from those of one-dimensional planar shocks. The implications of our results in space plasmas [viz. star formation, supernovae explosion, solar wind, pulsar magnetosphere, Saturn’s outer magnetosphere (R ∼ 13 − 18 R S ,where R S is the radius of Saturn), Saturn’s inner magnetosphere (R < 9 R S , etc.)] and laboratory plas- mas (viz. laser-induced implosion, capsule implosion, shock tube, etc.), where superthermal electrons with two distinct temperatures occurs, a re briefly discussed. 2015 artículo científico 0103-9733 https://www.redalyc.org/articulo.oa?id=46433753014 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 |
