Description
To obtain precise and accurate information on the Ariel exoplanet host stars a wide variety of good quality data is needed. In particular, high SNR, high-resolution optical and near-infrared spectra are fundamental to derive homogeneous stellar parameters and abundances, that are crucial both to characterise the star and to better understand the exoplanetary information that will be obtained by Ariel.
In this talk, I will describe the activities of the Observations sub-Working Group of the Stellar Characterisation WG, from archival mining to new observation planning, the results achieved so far, and the future works foreseen.
