Abstract
Conclusions. Our study confirms and expands upon the chemical diversity seen in this complex stellar system. All elements studied to date show large abundance spreads which require contributions from both massive and low mass stars.

We wish to thank Dr. Stuart Ryder, from the Australian Gemini Office, for his assistance during the Phase II definitions of our Gemini/Phoenix observations, and also Dr. Javier Alonso-Garcia for providing us Fig. 2. We warmly thank Prof Gary da Costa for reading the manuscript and for his helpful comments and remarks. We also thank the anonymous referee for helping improving the paper. Based on observations obtained at the Gemini Observatory, which is operated by the AURA, Inc., under a cooperative agreement with the NSF on behalf of the Geminipartnership: the NSF (United States), the STFC (United Kingdom), the NRC (Canada), CONICYT (Chile), the ARC (Australia), CNPq (Brazil) and SECYT (Argentina). This paper uses data obtained with the Phoenix infrared spectrograph, developed and operated by the National Optical Astronomy Observatory. The spectra were obtained as part of the program GS-2009A-Q-26.
