Imaging and Polarimetry of the Dust Shells Around Post-AGB Stars
Published online by Cambridge University Press: 26 May 2016
Abstract
We have completed a polarimetric survey of 46 post-AGB stars which indicates that where an extended circumstellar envelope is seen then it is axisymmetric to some degree. This suggests that all post-AGB envelopes are axisymmetric and that the responsible mechanism must be ubiquitous.
