The oxygen and neon abundances in planetary nebulae: implications for stellar nucleosynthesis
Abstract
The oxygen and neon abundances of 171 planetary nebulae located in the Galaxy, the Large and Small Magellanic Clouds and M31 have been calculated, using published spectrophotometric data. The resulting abundances of these two elements exhibit a strong linear relation between them which appears to be universal in the sense that it is independent of the host galaxy. The average Ne/O by mass in planetary nebulae is found to be 0.21. The Ne–O relation closely matches the one observed in extragalactic H II regions which suggests that abundances of these elements in intermediate-mass stars are not altered significantly by nucleosynthesis above or below the levels originally present at the time of their birth. Nevertheless, the Ne–O relation does not rule out ON cycling as a nitrogen production mechanism in progenitors of planetary nebulae.

A correlation is observed between Ne/H and O/H abundance in PNe in the Galaxy, LMC, SMC and M31.
“A correlation is observed to exist between the Ne/H and O/H abundance in PNe in the Galaxy, LMC, SMC and M31, within a small but probably real spread”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
