J/AZh/78/807            Chemical composition of eta Ser        (Antipova+, 2001)

The chemical composition of the red giant eta Ser. Antipova L.I., Boyarchuk A.A. <Astron. Zh. 78, 807 (2001)> =2001AZh....78..807A =2001ARep...45..700A
ADC_Keywords: Stars, giant ; Spectroscopy ; Abundances Abstract: Table2 contains the results of an analysis of elemental abundances in the atmosphere of eta Ser - a red giant of spectral type K2IIIabCN1. The resulting atmosphere parameters correspond to a K0 giant, and the peculiarities of the star chemical composition provide evidence that the assignment of Eta Ser to a class of CN stars was erroneous.
