The Frequency of Carbon Rich Stars Among Extremely Metal Poor Stars
Abstract
We discuss the fraction of carbon stars (C-stars) and of C-enhanced stars among samples of candidate extremely metal poor (EMP: [Fe/H] ⩽−3.0 dex) stars selected from the Hamburg/ESO Survey (HES), obtaining a total for C-rich stars with [C/Fe] ⩾ +1.0 dex of 14.4±4%. We also present the key results of detailed abundance analyses of a sample of 14 C-stars selected in this way.
