Special Session SS33  3 Jul 2026

Pushing the frontiers: precision spectroscopy of FGK stars

Aims and scope

New instrumentation is advancing along two complementary directions: the production of large statistical samples and the pursuit of high spectral resolution, which in principle enables high precision. Yet, to achieve real progress in this latter, high spectral resolution must be accompanied by advances in spectral analysis. This special session aims to bring together contributions presenting NOVEL HIGH-PRECISION SPECTROSCOPIC METHODS and UPDATES IN LINE MODELING aimed at deriving accurate and precise stellar parameters and chemical abundances. The purpose of the session is not only to show achievements, but also to expose PROBLEMS that hamper accurate determinations; for instance disagreements between outcomes of diverse methods and models. This way, we seek to promote collaboration between the observational and theoretical areas at implementing possible solutions.
