It provides precise parameter and chemical abundance measurements for 19 red giants in CoRoT fields, including internal mixing analysis.
Findings
Accurate fundamental parameters for 19 red giants.
Chemical abundances of Li, CNO, Na, and 12C/13C ratios.
Insights into internal mixing processes.
Abstract
A precise characterisation of the red giants in the seismology fields of the CoRoT satellite is a prerequisite for further in-depth seismic modelling. The optical spectra obtained for 19 targets have been used to accurately estimate their fundamental parameters and chemical composition. The extent of internal mixing is also investigated through the abundances of Li, CNO and Na (as well as 12C/13C in a few cases).
