Detailed studies of star-planet systems in the PLATO era

Abstract: Over the past two decades, space-based photometry missions such as CoRoT, Kepler, and TESS have revolutionized asteroseismology, enabling stellar characterization with unprecedented precision. By studying stellar oscillations, akin to Earth's seismology, we gain access to the internal layers of distant stars, enabling us to constrain internal transport processes and refine stellar parameters such as mass, radius, and age. These advances have profound implications for the study of planetary systems, whose detection and characterisation greatly benefit from accurate knowledge of their host stars. At the dawn of the PLATO mission, I will present how my work on high-precision asteroseismic and evolutionary modeling improves the characterization of solar-like host-stars and, consequently, deepen our understanding of the evolution of their planetary systems.
