The non-LTE line formation of neutral carbon in late-type stars

Fabbian, Damian; Asplund, Martin; Carlsson, M.; Kiselman, D


Aims. We investigate the non-Local Thermodynamic Equilibrium (non-LTE) line formation of neutral carbon in late-type stars in order to remove some of the potential systematic errors in stellar abundance analyses employing CI features. Methods. The statistical equilibrium code MULTI was used on a grid of plane-parallel ID MARCS atmospheric models. Results. Within the parameter space explored, the high-excitation CI lines studied are stronger in non-LTE due to the combined effect of line source...[Show more]
