Query: An abundance study of the red giants in the seismology fields of the
  CoRoT satellite   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).
