Left panel: same as Fig. 1, but for model NS+SN. The prescriptions about Eu nucleosynthesis for model NS+SN are similar to those of model Mod2SNNS by Matteucci et al. (2014) , but it allows for inhomogeneous mixing in the early Galaxy. Right panel: same as left panel but for model NS+MRD. In this model we consider the production of Eu by NSMs with a delay of 100 Myr and also a production by MRD SN (10% of all SNe II) but only for Z< 10-3.
