To study the possible nucleosynthetic backgrounds of extremely metal-deficient, carbon-rich (EMDC) stars, we have conducted high-resolution spectroscopy of 26 candidate objects selected from HK-survey stars with [Fe/H]? -2.0. The aims of the analysis are: (a) to calculate abundances for the targets, including the CNO- and neutron-capture elements; (b) to monitor the radial velocities of the survey targets and another 17 bona fide EMDC stars to search for binarity.
