Description

In this talk, I will present an ongoing project on determining the chemical abundance of young stars with DR17. As a first approach, we selected a sample of nearly 200 fiducial members of the Orion Complex.

We used the Brussels Automatic Code for Characterizing High accUracy Spectra (BACCHUS) code and DR17 atmospheric parameters to determine the abundance of 16 iron (Fe) lines. We then compute the mean Fe abundance for each star, averaging the best-fitted lines. I will present our preliminary results for Orion and how we use them to extend our study to other star-forming regions and chemical elements.
