High-resolution spectroscopic observations of a new CH subgiant star: BD-03°3668.

PEREIRA C.B. and DRAKE N.A.

Abstract (from CDS):

This work reports on the discovery of a new CH subgiant star BD-03°3668 with a significant overabundance of the elements created by s-process nucleosynthesis, such as barium and lead. Its atmospheric parameters and abundance pattern are determined by employing the local thermodynamic equilibrium model atmospheres of Kurucz using the spectral analysis code MOOG. Due to the low luminosity of this star, the s-process overabundance is better explained by mass transfer from an asymptotic giant branch star in the past.
