Abundances of Galactic Anticenter Planetary Nebulae and the Oxygen Abundance Gradient in the Galactic Disk
R. B. C. Henry, Karen B. Kwitter, Anne E. Jaskot +3
We have obtained spectrophotometric observations of 41 anticenter planetary nebulae (PNe) located in the disk of the Milky Way. Electron temperatures and densities, as well as chem…
Alpha Element Abundances in a Large Sample of Galactic Planetary Nebulae
J. B. Milingo, K. B. Kwitter, R. B. C. Henry +1
We present emission line strengths, abundances, and element ratios (X/O for Ne, S, Cl, and Ar) for a sample of 38 Galactic disk planetary nebulae (PNe) consisting primarily of Peim…
Galactic Abundance Patterns via Peimbert Types I & II Planetary Nebulae
J. B. Milingo, K. B. Kwitter, R. B. C. Henry +1
Planetary Nebulae (PNe) abundance patterns have long been used to note signatures of nuclear processing and to trace the distribution of metals throughout galaxies. We present abun…
