  Connecting star and planet properties in a single model is not
straightforward. Stellar population synthesis models are key to explore
combined statistical constraints from stars and planets observations. The
Besan\c{c}on stellar population synthesis model (Robin et al. 2003, Lagarde et
al. 2017) includes now the stellar evolutionary tracks computed with the
stellar evolution code STAREVOL (Lagarde et al. 2012, Amard et al. 2016). It
provides the global (M, R, Teff, etc) and chemical properties of stars for 54
chemical species. It enables to study the different galactic populations of the
Milky Way (the halo, the bulge, the thin and thick disc) and a specific
observational survey. Here, we couple the Besan\c{c}on model with a simple
stoichiometric model (Santos et al. 2017) in order to determine the expected
composition of the planet building blocks (PBB). We investigate the trends and
correlations of the expected chemical abundances of PBB in the different
stellar populations of the Milky Way (Cabral et al. 2018).
