Magnetic Fields in Circumstellar Envelopes of Evolved AGB Stars
Magnetic Fields in Circumstellar Envelopes of Evolved AGB Stars
In this paper, a time-dependent magnetohydrodynamic model is presented which aimed at understanding the superwind production by an evolved AGB star and the consecutive formation of a dense circumstellar envelope (CSE) around it. We know henceforth from various observations that a large scale magnetic field, probably toroidal in shape, is …
