Abstract
The abundances of Fe, C, N, and Ba have been derived for the Carbon-Enhanced Metal-Poor star HE 1305+0132. The C and N abundances are typical of CEMP stars. The Ba abundance, derived for the first time for HE 1305+0132, is found to be enhanced relative to Fe, placing this star in the CEMP-s group. Combined with a previously derived highly enhanced abundance of F, the chemical composition of HE 1305+0132 strongly suggests that it has been polluted via mass transfer by a more evolved companion as it passed through its asymptotic giant branch phase.
