摘要

In the present work, we have discussed the effects of adiabatic trapping of electrons on obliquely propagating Alfven waves in a low beta plasma. Using the two potential theory and employing the Sagdeev potential approach, we have investigated the existence of arbitrary amplitude coupled kinetic Alfven-acoustic solitary waves in both the sub and super Alfvenic cases. The results obtained have been analyzed and presented graphically and can be applied to regions of space where the low beta assumption holds true.
