【 摘 要 】
We investigate the metallicity distribution function (MDF) of the Galactic halo and the relative fraction of Carbon-normal and Carbon-rich stars using the semi-analytical code GAMETE. The code reconstructs the hierarchical merger tree of the Milky Way (MW) and follows the star formation history and the metal evolution in individual progenitors, including for the first time the formation and evolution of dust. We predict scaling relations between the dust, metal and gas masses for MW progenitors and compare them with observational data of galaxies at 0 ≤ z
