- Abstract
Recent studies have shown that the extended circumstellar envelopes of AGB stars are not always spherical in shape. Moreover, the majority ofpost-AGB stars exhibit highly aspherical shapes, such as bipolar nebulaeand equatorial waists in the form of dusty and gaseous disks and/or tori. As such, one should expect that the origin of the morphological changes seen in later evolutionary stages can be traced during the AGB phase. We now present a study of AGB stars using aperture masking interferometry to resolve such aspherical structures.
