Planetary Nebulae in the Magellanic Clouds: Probing Stellar Evolution and Populations
نویسنده
چکیده
This review contains: (1) the scientific motivations for studying Planetary Nebulae in the Magellanic Clouds; (2) a review of this field of study, from the origins to the most recent results, focusing on the papers that have been published since the last IAU Symposium on Planetary Nebulae; (3) a review of the Hubble contribution to the field, from the early results to our own Magellanic Cloud Planetary Nebula program.

Magellanic Clouds Planetary Nebulae: an Updated View on Stellar Evolution and Populations
El resumen será traducido al español por los editores. Planetary Nebulae (PNs) in the Magellanic Clouds are studied to understand stellar populations and evolution of lowand intermediate-mass stars in different chemical environments. Using HST observations from our LMC and SMC PN morphological survey and from the HST Data Archive, we look at the relations between PN morphology and their evoluti...
متن کاملPlanetary nebulae as probes of the chemical impact of AGB stars
Planetary nebulae (PN) represent the evolutionary fate of the asymptotic giant branch (AGB) stellar envelopes, thus are ideally suited to study the chemical impact of AGB stars. Stellar evolution predict elemental enrichment through the AGB evolution, and convective dredge-up episodes allow the products of stellar evolution to reach the stellar outer layers. Planetary nebulae are probes of thes...
متن کاملPlanetary Nebulae in the Magellanic Clouds
The proximity, accurately known distance and low line-ofsight reddening give the ideal circumstances to pursue studies of individual stellar populations in the Magellanic Clouds. Here we show how our understanding of the evolution and chemical composition of the planetary nebulae in the Magellanic Clouds has been impacted by imaging and UV spectroscopic studies using the Hubble Space Telescope....
متن کاملPlanetary Nebulae as Probes of Stellar Evolution and Populations
Planetary Nebulae (PNe) have been used satisfactory to test the effects of stellar evolution on the Galactic chemical environment. Moreover, a link exists between nebular morphology and stellar populations and evolution. We present the latest results on Galactic PN morphology, and an extension to a distance unbiased and homogeneous sample of Large Magellanic Cloud PNe. We show that PNe and thei...
متن کاملClues on post-Asymptotic Giant Branch Evolution and Planetary Nebulae Populations from the Magellanic Clouds
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 emissi...
