The origin of carbon, investigated by spectral analysis of solar-type stars in the Galactic Disk.

GUSTAFSSON B., KARLSSON T., OLSSON E., EDVARDSSON B. and RYDE N.

Abstract (from CDS):

Abundance analysis of carbon has been performed in a sample of 80 late F and early G type dwarf stars in the metallicity range -1.06≤[Fe/H]≤0.26 using the forbidden [C I] line at 8727Å. This line is presumably less sensitive to temperature, atmospheric structure and departures from LTE than alternative carbon criteria. We find that [C/Fe] decreases slowly with increasing [Fe/H] with an overall slope of -0.17±0.03. Our results are consistent with carbon enrichment by superwinds of metal-rich massive stars but inconsistent with a main origin of carbon in low-mass stars. This follows in particular from a comparison between the relation of [C/O] with metallicity for the Galactic stars and the corresponding relation observed for dwarf irregular galaxies. The significance of intermediate-mass stars for the production of carbon in the Galaxy is still somewhat unclear.
