Talk abstract details

While strong magnetic fields are shown to be ubiquitous in the envelopes of AGB and post-AGB stars, their origin and role in PNe formation is still unclear. I will present the currently available observations of circumstellar envelope magnetic fields. I will also discuss the possibilities that will be offered by the next generation of telescopes, in particular ALMA, in determining the origin and the effect of magnetic fields on the mass-loss process and on the shaping of PNe.
