12C/13C in atmospheres of red giants and peculiar stars
Yakiv V. Pavlenko
We determine the carbon isotopic ratios in the atmospheres of some evolved stars in both globular clusters and the disk of our Galaxy. Analysis of 12CO and 13CO bands at 2.3 micron…

Carbon abundances and 12C/13C from globular cluster giants
Yakiv V. Pavlenko, Hugh R. A. Jones, Andrew J. Longmore
The behaviour of the Delta nu =2 CO bands around 2.3 micron was examined by comparing observed and synthetic spectra in stars in globular clusters of different metallicity. Changes…
