Chemical connections between low-mass stars and planets building blocks investigated by stellar population synthesis
Abstract
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 Besançon stellar population synthesis model includes now the stellar evolutionary tracks computed with the stellar evolution code STAREVOL. 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 Besançon model with a simple stoichiometric model 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).
