We present the first time abundance analysis of a very metal-poor carbon-enhanced star CD - 27 14351 based on a high resolution ( R { \sim } 48 000 ) FEROS spectrum .
Our abundance analysis performed using Local Thermodynamic Equilibrium ( LTE ) model atmospheres shows that the object is a cool star with stellar atmospheric parameters , effective temperature T _ { eff } = 4335 K , surface gravity log g = 0.5 , microturbulence \xi = 2.42 km s ^ { -1 } , and , metallicity [ Fe/H ] = - 2.6 .
The star exhibits high carbon and nitrogen abundances with [ C/Fe ] = 2.89 and [ N/Fe ] = 1.89 .
Overabundances of neutron-capture elements are evident in Ba , La , Ce , and Nd with estimated [ X/Fe ] > 1 , the largest enhancement being seen in Ce with [ Ce/Fe ] = 2.63 .
While the first peak s-process elements Sr and Y are found to be enhanced with respect to Fe , ( [ Sr/Fe ] = 1.73 and [ Y/Fe ] = 1.91 ) the third peak s-process element Pb could not be detected in our spectrum at the given resolution .
Europium , primarily a r-process element also shows an enhancement with [ Eu/Fe ] = 1.65 .
With [ Ba/Eu ] = 0.12 the object CD - 27 14351 satisfies the classification criterion for CEMP-r/s star .
The elemental abundance distributions observed in this star is discussed in light of chemical abundances observed in other CEMP stars from literature .
