A carbon rich star BD+75 348: a binary?
ZACS L., SCHMIDT M.R. and SCHUSTER W.J.
Abstract (from CDS):
An LTE abundance analysis of the ``CH-like" star BD+75 348, with an unknown evolutionary status, is presented based on high resolution, high signal-to-noise spectra. With [C/Fe]=+0.5dex and a mean s-process overabundance of [s/Fe]≃+1.6dex the peculiar atmospheric composition of BD+75 348 is confirmed. The modest iron deficiency, [Fe/H]=-0.8, and the kinematic data support the idea that BD+75 348 is an old disk population object. Possible evolutionary stages, that can explain its atmospheric parameters and peculiar chemical composition, are discussed.
