From Historical Perspectives to Some Modern Possibilities

Astrophysics 2007-05-23 v1

Abstract

A historical perspective on the study of asymmetries in planetary nebulae (PNs) is presented. We also describe our ongoing work in high resolution spectroscopy of planetaries, and discuss some likely future directions for the study of asymmetrical PNs.
