The Formation of Fullerenes in Planetary Nebulae
Galaxies, 2018 In the last decade, fullerenes have been detected in a variety of astrophysical environments, with the majority being found in planetary nebulae. Laboratory experiments have provided us with insights into the conditions and pathways that can lead to ...

On the Origin of Planetary Nebulae [PDF]
Progress of Theoretical Physics, 1962 A hypothesis that planetary nebulae originate from red giants when tl:e helium burning begins in the degenerate helium core is proposed and examined quantitatively. It is assumed that the shock wave is generated by the rapid core expansion which is caused by the removal of degeneracy at the helium core.

Planetary Nebulae: Sources of Enlightenment [PDF]
Publications of the Astronomical Society of the Pacific, 2021 In this review/tutorial we explore planetary nebulae as a stage in the evolution of low-to-intermediate-mass stars, as major contributors to the mass and chemical enrichment of the interstellar medium, and as astrophysical laboratories.

Emerging Minds Journal for Student Research, 2023 This project compares two planetary nebulae (NGC 1514 and NGC 40) and studies the difference between them in their chemical composition. Observations of the two planetary nebulae were done at Clanfield Observatory with the 24-inch Ritchey-Chrétien ...

Abell 30 - A binary central star among the born-again planetary nebulae [PDF]
, 2020 Eight planetary nebulae have been identified as `born-again', a class of object typified by knotty secondary ejecta having low masses ($\sim$$10^{-4}$ M$_{\odot}$) with nearly no hydrogen.

Lessons from the Ionised and Molecular Mass of Post-CE PNe
Galaxies, 2022 Close binary evolution is widely invoked to explain the formation of axisymmetric planetary nebulae after a brief common envelope phase. The evolution of the primary would be interrupted abruptly, its still quite massive envelope being fully ejected to ...

The Importance of Binarity in the Formation and Evolution of Planetary Nebulae [PDF]
The Impact of Binary Stars on Stellar Evolution, 2018 It is now clear that a binary evolutionary pathway is responsible for a significant fraction of all planetary nebulae, with some authors even going so far as to claim that binarity may be a near requirement for the formation of an observable nebula.
