High-resolution spectra were obtained with the VLT UVES spectrograph in the framework of the Gaia-ESO Survey. The stars in our sample can be separated into two groups with a difference of 0.1 dex in the mean metallicity, 0.3 dex in the mean C/N, and no significant difference in the mean values of C+N+O.Stars abundancesstars evolutionglobular clusters individual (NGC 1851)10.1017/S1743921315007048http://adsabs.harvard.edu/abs/2016IAUS..317..352T2016IAUS..317..352T
