Abstract:
Becau se of their common origin\, it is expected (or assumed) that the compositi on of planet building blocks should (to a first order) correlate with stel lar atmospheric composition\, especially for refractory elements.

In fact\, information on the relative abundance of refractory and major rock-forming elements such as Fe\, Mg\, Si are commonly used to improve in terior estimates for terrestrial planets and has even been used to estimat e planet composition in different galactic populations.

However\ , there is no direct observational evidence for the aforementioned expecta tion/assumption and was even recently questioned. In this talk I'\;ll present our latest results where showed that the composition of the planet building blocks indeed correlates with the properties of the rocky planet s.
