Testing common-envelope binary evolution with measurements of the C-12/C-13 isotopic ratios
We carried out medium resolution spectroscopy of close, detached white dwarf - red dwarf binaries without planetary nebulae and cataclysmic variables in the infra-red K-band (2.3 - 2.4 mum). We have detected the (CO)-C-12 bands at 2.3535 mum and 2.3829 mum and, for the first time, the (CO)-C-13 band...
