Stardust in Stellar Births, Deaths and Binaries

摘要

Dusty astrophysical systems, including young stellar objects, evolved late-type stars and colliding-wind binaries have all proved ready targets for interferometric imaging studies. New results from the established aperture masking project operating in the near-infrared on the Keck-I telescope are presented. A number of objects exhibit detailed morphologies and motions of circumstellar material which convey a great deal of astrophysical insight. Such results give a preview of the immense potential of the new generation of interferometers capable of going beyond the brightest few prototypical sources presented here.
