The nitrogen abundance of the very metal-poor star HD 122563.
Abstract
The nitrogen abundance for the very metal-poor giant HD 122563 has been determined, using new spectroscopic plate data of the CH, NH, and CN molecular bands and a spectrum synthesis analysis. The results indicate that nitrogen is overabundant by a factor of 15 relative to iron, while carbon is underabundant by a factor of 3. Account has been taken of the influence of the unknown oxygen abundance on the carbon equilibrium. Subject headings: abundances, stellar - late-type stars - stars, individual - weak-line stars

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.
