Clues on Post-Asymptotic Giant Branch Evolution and Planetary Nebulae Populations from the Magellanic Clouds

Abstract

Abstract.The recent HST optical images, and the optical and ultraviolet spectra, of Magellanic planetary nebulae (PNe), together with the large data-base that has been collected in the past decade, allows unprecedented insight in the evolution of PNe and their central stars. In this paper we present a selection of recent results: The analysis of PN morphology, both in the optical and ultra-violet emission lines; the relation between nebular morphology and the chemistry produced by stellar evolution; the direct determination of the transition time from observations; and the study of the nature and evolutionary stage of the components of the planetary nebula luminosity function.
