Abstract: Carbon-enhanced metal-poor (CEMP) stars are now accepted to be mass-transferred binary members of the first generation of stars. Indeed, the peculiar chemical fingerprints revealed by their spectra represent a unique opportunity to study their now extinct progenitors (basically all low-metallicity stars with M > 0.8 M) and the early stages of the Galaxy. In the context of the currently existing high-quality spectrographs and large surveys, many spectra of CEMP stars have now been observed, and they tell us about the physics of the first generations of AGB stars. Here we present abundances derived from the challenging spectra of these stars.
