Description
Homogeneous and precise measurements of elemental abundances in planet-hosting Ariel targets are essential for accurately characterizing planetary properties and for providing key constraints on planet formation and evolution processes. In this talk, I will present results from the Elemental Abundance sub-working group of the Ariel Stellar Characterization Working Group, focusing on homogeneous and precise determinations of volatile and refractory element abundances (Na, Mg, Al, Si, S, Ti, Ni, Y) derived from high-resolution spectroscopy. I will discuss the relationships between elemental abundance ratios and explore their possible connections with planetary properties, paying attention to planet-hosting stars belonging to the Galactic thin and thick disks, and considering potential differences linked to their distinct formation histories.
