Recent studies of the Milky Way and its satellites have paid special attention to the importance of carbon-enhanced metal-poor ( CEMP ) stars due to their involvement in Galactic formation history and their possible connection with the chemical elements originating in the first stellar generation .
In an ongoing study of red giants in the Sculptor dwarf galaxy we have discovered a star with extremely strong CN and CH molecular bands .
This star , Scl-1013644 , has previously been identified by as a star with an enrichment in the heavy elements .
Spectrum synthesis has been used to derive the carbon , nitrogen and barium abundances for Scl-1013644 .
Our findings are [ C/Fe ] = +0.8 , [ N/Fe ] = –0.3 and [ Ba/Fe ] = +2.1 with the latter result consistent with the value found by .
These results reveal Scl-1013644 as a CEMP-s star , the third such star discovered in this dwarf galaxy .
