Time dependent nonplanar DIA shock waves in multi-component dusty plasmas with distinct temperature superthermal electrons

Summary form only given. The basic characteristics of nonplanar dust-ion-acoustic (DIA) shock waves in a multi component electron-positron-ion dusty plasma (consisting of inertial ions, electrons of two distinct temperatures referred to as low and high temperature kappa distributed superthermal electrons, Boltzmann distributed positrons, and negatively charged immobile dust grains) has been investigated both theoretically and analytically. The hydrodynamic equation for inertial ions has been used to derive the modified Burgers equation. The influence of double temperature superthermal electrons, Maxwellian positrons and ion kinematic viscosity on the cylindrical and spherical DIA shock waves, are briefly discussed. The present investigation can be very effective for studying and understanding the basic characteristics of nonplanar shock wave propagation through different astrophysical situations.
