| Abstract: | Ci, Ni, andOi permitted and forbidden lines in the near-infrared spectra of Procyon (F5 IV–V), Sun (G2 V), and Arcturus (K2 IIIp) have been analyzed to determine their carbon, nitrogen, and oxygen abundances. Procyon is found to have normal abundances while Arcturus is found to have an enhanced nitrogen abundance by a factor of 1.03 dex relative to the Sun. The dependence of the derived abundances on the effective temperature and luminosity is investigated.Much of the work reported here was contained in the Ph.D. thesis of the author submitted to the Istanbul University, Turkey, in 1986. |
