Carbon stars within the Gaia-ESO survey

Abia, Carlos (Universidad de Granada, Spain)

We present the detection and chemcial analysis of carbon-enriched stars within the Gaia-ESO survey. In a first step, carbon-enriched candidates are detected from the analysis of a series of enhanced molecular features, measured through narrow-band spectroscopic filters. Then, the atmospheric parameters, C/O ratios and s-process element abundances are determined. The nature of these carbon-enriched stars is discussed together with expected impact of the Gaia mission on the knowledge of these objects in the Milky Way..
