Scl-1013644: a CEMP-s star in the Sculptor Dwarf Spheroidal Galaxy
  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 Geisler et al. (2005) 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 Geisler et al. (2005). These results reveal
Scl-1013644 as a CEMP-s star, the third such star discovered in this dwarf
galaxy.
