The Ionization State of the Halo Planetary Nebula NGC 2438

open access: yes, 2011
NGC 2438 is a classical multiple shell or halo planetary nebula (PN). Its central star and the main nebula are well studied. Also it was target of various hydrodynamic simulations (Corradi et al. 2000).

Planetary Nebulae: An Introductory Review [PDF]

open access: yesSymposium - International Astronomical Union, 1983
Planetary nebulae constitute a popular field of investigation because they offer a unique opportunity to study the final stages of stellar evolution before a star dies. They supply challenges not only to the stellar evolution expert but also to the spectroscopist, to the student of galactic structure, and to all observers, whether one works in the ...

Outflowing Gas in the Planetary Nebula K 3-54

open access: yesThe Astronomical Journal
As planetary nebulae evolve, they develop slow and strong dust-driven stellar winds, making the joint study of dust and gas essential for understanding their nature.

Primer on Formation and Evolution of Hydrogen-Deficient Central Stars of Planetary Nebulæ and Related Objects

open access: yesGalaxies
We present a brief review of the formation and evolution of hydrogen-deficient central stars of planetary nebulae. We include a detailed description of the main observable features of both the central stars and their surrounding nebulae and review their ...

Evidence for a Binary origin of the Young Planetary Nebula HB 12 [PDF]

open access: yesarXiv, 2006
Young planetary nebulae play an important role in stellar evolution when intermediate- to low-mass stars (0.8 ~ 8 M) evolve from the proto-planetary nebulae phase to the planetary nebulae phase. Many young planetary nebulae display distinct bipolar structures as they evolve away from the proto-planetary nebulae phase.
