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 ...

Star Counts across the Red Giant Branch Bump and Below

The Astrophysical Journal, 2001
We present a new observable?Rbump?which is the ratio between the star counts across the red giant branch (RGB) bump and fainter RGB stars to investigate the occurrence of a deep-mixing phenomenon during these evolutionary phases. The comparison between predicted and empirical Rbump-values, based on a large and homogeneous set of Hubble Space Telescope ...
