In the last decade or so a variety of ground based spectroscopic surveys of the Milky Way have been undertaken. These projects are yielding accurate kinematics and abundances for large, statistically significant samples of stars belonging to different Galactic populations.
I will review the main results from those surveys, and discuss their huge impact on our understanding of the chemical and...

I will discuss the Eu production in the Milky Way under different assumptions about its nucleosynthesis. In particular, Eu formation via merging neutron stars and supernova core-collapse will be discussed in the light of the results from a detailed chemical evolution model that will be compared with the abundances of Eu in stars of the solar vicinity.The formation of Eu via merging neutron...

The origin of the heaviest elements is still a matter of debate. For the rapid neutron capture process (r -process), multiple sites have been proposed, e.g., neutron star mergers and (sub-classes) of supernovae. R-process elements have been measured in a large fraction of metal-poor stars. Galactic archaeology studies show that the r-process abundances among these stars vary by over 2 orders...
