Concluding discussion
11:20 - 12:00
Each participant will be asked to answer in a few written lines the two following questions: 1) What is the most interesting thing she/he has learnt during the conference? 2)What non-answered question(s) she/he would like to study in the coming years about CEMP stars? The answers will be collected and a SOC member will prepare a small presentation to share the results with the audience.
