摘要

In this article, a magnetohydrodynamic (MHD) model is presented that is aimed at understanding the anisotropic mass loss by an AGB star and subsequent bipolar planetary nebula formation. The main challenge in developing such a model was to simultaneously treat the dynamo engine in the core region of the AGB progenitor, magnetic buoyancy, meridional circulation, and gas ejection in a self-consistent manner. A previous article did not incorporate the dynamo and the feedback of the produced magnetic field on differential rotation.
