During their late stages of evolution, stars of roughly 1 solar                 mass eject their outer, hydrogen-rich envelopes and thereby                     produce so-called planetary nebulae (i.e., expanding gaseous                    shells that, despite the nomenclature, have nothing to do with                  planets).  The remaining stellar cores (i.e., the central stars of              the planetary nebulae) consist predominantly of helium, though                  heavier elements may be present as well.                                                                                                                        The Principal Investigator proposes to study the formation of                   planetary nebulae and the evolution of their central stars, with                particular attention paid to determining the elemental abundances               present in the precursor stars, the nebulae, and the central stars              of planetary nebulae.  The work will include the compiling of a                 "Catalogue of Spectrum Line Intensities" of planetary nebulae.
