The main goal of the workshop is the preparation of two observing proposals aimed to investigate: (a) the origin and evolution of the r-process elements in the EMP stars; (b) the origin of multiple stellar populations (MPs) in the Galactic globular clusters (GGCs); and (c) to exchange ideas regarding the possible future observing proposals related to the study of EMP stars, as well as MPs in the GGCs. Several broader review talks will set up the stage for an in-depth discussions of the two observing proposals. Separate slots will be reserved for in-depth discussions to plan future observing proposals. The largest fraction of the workshop time will be devoted to hands-on activities for writing the two observing proposals that will be submitted during the Period 104 call for proposals at ESO (March 2019).
