【 摘 要 】

Ion-Acoustic (IA) shock waves are studied in a magnetized, five component cometary plasma consisting of positively and negatively charged oxygen ions, kappa described hydrogen ions, hot solar electrons and slightly colder cometary electrons. The Korteweg-de Vries-Burgers (KdVB) equation is derived and the variation of the shock profile is studied. It is found that the obliqueness of shock wave propagation significantly varies the basic properties like amplitude and width of the shock.
