Abstract (from CDS):

We present an analysis of a high-resolution (R ≃ 40000) infrared spectrum of the RS Oph secondary around the first overtone CO bands, obtained in 2008 May on the Gemini-South 8m telescope. The 12CO and 13CO bands are well resolved, and we compute synthetic spectra to determine the 12C/13C ratio. We find 12C/13C ≃ 16±3, consistent with the interpretation of the secondary as a red giant which has evolved beyond the first dredge-up phase of evolution.
