Abstract
Nearly 30 years ago our understanding of planetary systems and the potential for life beyond Earth was revolutionized by the discovery of Pegasi 51 b, the first exoplanet orbiting a main sequence star. From that historical moment, several space- and ground-based missions contributed to the detection of almost 6000 new worlds orbiting stars other than our Sun. The European Space Agency's PLAnetary Transits and Oscillations of stars (PLATO) mission, is designed to detect and characterize exoplanets around bright, nearby stars with a special target: a twin of our own planet. PLATO's unique combination of long-term, high-cadence photometry and detailed asteroseismic analysis will enable the determination of stellar and planetary parameters with high accuracy. A key aspect of this work is the exploration of PLATO’s synergy with other space- and ground-based missions, such as TESS (Transiting Exoplanet Survey Satellite), CHEOPS (CHaracterising ExOPlanets Satellite), and JWST (James Webb Space Telescope). This collaboration enhances PLATO’s scientific output by providing complementary observations that improve the identification and characterization of exoplanetary candidates. This Thesis also explores the hot Neptune and sub-Jovian desert, a region in parameter space where planets are unexpectedly rare, and investigates its implications for planetary formation and evolution. Furthermore, citizen science initiatives are explored as an innovative tool for maximizing the scientific return of the mission by involving the public in the detection and analysis of exoplanetary signals. By leveraging PLATO’s advanced capabilities and its collaborative potential with other missions, this Thesis contributes to the broader understanding of exoplanet demographics and the search for life-sustaining worlds beyond our Solar System.
