Abstract:
New red and violet system line lists for the CN isotopologues
13C14N and 12C15N have been generated. These new transition
data are combined with those previously derived for 12C14N, and
applied to the determination of CNO abundances in the solar
photosphere and in four red giant stars: Arcturus, the bright, very
low-metallicity star HD 122563, and the carbon-enhanced metal-poor
stars HD 196944 and HD 201626. When both red and violet system lines
are detectable in a star, their derived N abundances are in good
agreement. The mean N abundances determined in this work are also
generally in accord with published values.
Description:
Line lists for 13C14N and 12C15N were computed in the same way
as described by Brooke et al. (2014, Cat. J/ApJS/210/23), using
identical dipole moment functions and Rydberg-Klein-Rees (RKR)
potential energy curves as adopted for 12C14N.
