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 .
