Planetary Nebulae: Sources of Enlightenment [PDF]
PASP, 134, Number 022001, 2022, 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. We discuss many observed properties of planetary nebulae, placing particular emphasis on element abundance ...

Surveying Planetary Nebulae Central Stars for Close Binaries: Constraining Evolution of Central Stars Based on Binary Parameters [PDF]
Galaxies, 2018 The increase in discovered close binary central stars of planetary nebulae is leading to a sufficiently large sample to begin to make broader conclusions about the effect of close binary stars on common envelope evolution and planetary nebula formation ...

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 ...

Planetary Nebulae Research: Past, Present, and Future [PDF]
GalaxiesWe review the evolution of our understanding of the planetary nebulae phenomenon and their place in the scheme of stellar evolution. The historical steps leading to our current understanding of central star evolution and nebular formation are discussed ...

Planetary Nebulae Shaped by Common Envelope Evolution [PDF]
Galaxies, 2018 The morphologies of planetary nebula have long been believed to be due to wind shaping processes in which a “fast wind„ from the central star impacts a previously ejected envelope.

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 ...

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 ...

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.

Conservation Science and Practice, Volume 4, Issue 12, December 2022., 2022 People perceiving environmental degradation, and losses of economic growth, nature‐based recreation opportunities, health, and knowledge as consequences of biodiversity loss were more likely to support the prohibition of illegal wildlife consumption. People consuming bushmeat frequently and supporting the biodiversity loss preventive measure seemed 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.
