Title: Sun-like stars with Earth-like and Mercury-like planets
Abstract:
Because of their common origin, it is expected (or assumed) that the composition of planet building blocks should (to a first order) correlate with stellar 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 interior estimates for terrestrial planets and has even been used to estimate planet composition in different galactic populations. However, there is no direct observational evidence for the aforementioned expectation/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 planets.
