Clues on post-Asymptotic Giant Branch Evolution and Planetary Nebulae Populations from the Magellanic Clouds
Letizia Stanghellini
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…
Magellanic Cloud planetary nebulae as probes of stellar evolution and populations
Letizia Stanghellini
Planetary Nebulae (PNs) in the Magellanic Clouds offer the unique opportunity to study both the population and evolution of low- and intermediate-mass stars, in an environment that…
Magellanic Cloud PNs as probes of stellar evolution and populations
Letizia Stanghellini
Magellanic Cloud Planetary Nebulae (PNs) offer insight of both the population and evolution of low- and intermediate-mass stars, in environments that are free of the distance bias…
Magellanic Clouds Planetary Nebulae: an updated view on stellar evolution and populations
Letizia Stanghellini, Richard A. Shaw, Max Mutchler
Planetary Nebulae (PNs) in the Magellanic Clouds are studied to understand stellar populations and evolution of low- and intermediate-mass stars in different chemical environments.…
Morphology and Evolution of LMC Planetary Nebulae
Richard A. Shaw, Letizia Stanghellini, Max Mutchler +2
The LMC is ideal for studying the co-evolution of planetary nebulae (PNe) and their central stars, in that the debilitating uncertainties of the Galactic PN distance scale and sele…
Measurements of 12C/13C ratio in planetary nebulae: implications on stellar and Galactic chemical evolution
F. Palla, R. Bachiller, L. Stanghellini +2
We present the results of a study aimed at determining the 12C/13C ratio in two samples of planetary nebulae (PNe) by means of millimeter wave observations of 12CO and 13CO. The fi…
