摘要：

In the present investigation, we have studied the effect of trapping on ion acoustic (IA) shock waves with quantizing magnetic field in quantum plasma composed of degenerate electrons/positrons and cold inertial ions. We have derived KdV-Burgers (KdVB) equation by employing the reductive perturbation method and also presented its exact solution. It is observed that positron to electron concentration (via delta), quantizing magnetic field (via rho), and finite electron temperature (via T) have a empathetic influence on IA shock structures in the nonlinear regime. Both polarity shock structures have been found in the given system. The work presented in this investigation may be useful to studying the salient feature of IA shocks dynamics in astrophysical dense plasma environments especially in white dwarfs, etc.
