Spectroscopic characterization of solar-type targets in the first long-duration PLATO field

The PLATO mission, scheduled for launch by ESA at the end of 2026, will bring a revolution in our understanding of extrasolar planets, as it will characterize exoplanetary systems with a precision never achieved before. This work aims to provide a detailed characterization of one hundred solar-type targets in the first long-duration PLATO field. The analysis is based on new observations gathered with the STELLA-SES échelle spectrograph, along with TESS and Gaia DR3 data. The study focuses on various factors that could influence exoplanet detection, as well as the characteristics of potential planetary systems. These include stellar features, activity and age, and presence of companions.
