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...

7. Ariel stellar characterisation - updating the CNO abundances of the mission canditate sample

Ronaldo Oliveira da Silva (Istituto Nazionale di Astrofisica (INAF))

The derivation of elemental abundances for the stars belonging to the Ariel mission candidate sample is an ongoing task under the responsibility of the Stellar Characterisation Working Group. In da Silva et al. (2024), we published the first results regarding the abundances of carbon, nitrogen, and oxygen for a subsample of 181 FGK dwarf stars with stellar parameters (effective temperature,...
