Abstract:
We report on medium-resolution near-IR spectroscopy of a sample of over 60 Carbon-
Enhanced Metal-Poor (CEMP) stars observed with SOAR/OSIRIS, selected from the HK survey
of Beers and colleagues and the Hamburg/ESO Survey of Christlieb and colleagues. Oxygen
abundances from the molecular CO lines as well as rough estimates of 12C/13C ratios are estimated
from the near-IR spectra of these stars. Near-IR model spectra with varying oxygen
abundances, in combination with previously determined parameters from optical spectra are
used for the estimation of abundances for this sample. As both oxygen abundances and 12C/13C
ratios are tracers of nucleosynthesis, we hope to gain information about Galactic nucleosynthesis
through the analysis of this sample.
