Carbon Abundances of M92 Red Giant Branch Stars

Publications of the Astronomical Society of the Pacific, 2001
Using CCD imaging, Fusi Pecci et al. have identified a local maximum at MV = -0.4 in the giant branch luminosity function of three co-added globular clusters having metallicities [Fe/H] ~ -2.2, including M92 (NGC 6341). Theories of deep mixing predict that surface carbon abundance depletions should be produced only within stars brighter than this ...

Evidence for non-standard mixing on the red giant branch

2008
Based on the new grid of standard stellar models computed at solar metallicity by the Geneva group (Schaller et al. 1992) with the recent OPAL opacity tables (Rogers & Iglesias 1992), we follow the theoretical evolution of the 12C/13C ratio along the red giant branch of low and intermediate mass stars.
