Ultraviolet NH bands as indicators of nitrogen abundance in the atmospheres of cool stars.
Abstract
Nitrogen abundance indicators were selected for spectral resolutions of 0.0025 nm and 0.02 nm in the NH band region at λ336 nm. For this purpose a list of atomic lines from LOWLINES, DAT (CD-ROM No. 1 in Kurucz's 1993 database) and lists of molecular lines from CD-ROM No. 18 were tested and corrected using the spectrum of the Sun as a star. The effect of line list completeness on nitrogen abundance estimates is examined.
