| dc.description.abstractEn | Our Galaxy is composed of different stellar populations with varying chemical abundances, which are thought to imprint the composition of planet building blocks (PBB). We aim to determine the PBB metallicity trends by using the GALAH large spectroscopic survey. We assess the reliability of the composition of PBB as determined with a propagation error study. Despite of the large uncertainties on molecular mass fractions, we find robust overall trends with metallicity. | |
