Carbon-enhanced metal-poor stars in the SDSS-APOGEE database
  We identify six new CEMP stars ([C/Fe]>+0.7 and [Fe/H]< -1.8) and another
seven likely candidates within the APOGEE database following Data Release 12.
These stars have chemical compositions typical of metal-poor halo stars, e.g.,
mean [$\alpha$/Fe] = +0.24$\pm$0.24, based on the ASPCAP pipeline results. A
lack of heavy element spectral lines impedes further sub-classification of
these CEMP stars, however, based on radial velocity scatter, we predict most
are not CEMP-s stars which are typically found in binary systems. Only one
object, 2M15312547+4220551, may be in a binary since it exhibits a scatter in
its radial velocity of 1.7 $\pm$0.6 km s$^{-1}$ based on three visits over a
25.98 day baseline. Optical observations are now necessary to confirm the
stellar parameters and low metallicities of these stars, to determine the
heavy-element abundance ratios and improve the precision in the derived
abundances, and to examine their CEMP sub-classifications.
