| 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. |
