Asteroseismology in PLATO. A necessary tool for characterizing planetary systems

Today, the field of stellar physics is witnessing a significant boost thanks to the progress of asteroseismology from space with satellites like CoRoT and Kepler, which will be exploited to its full power with the PLATO mission now under development. Both the study of stellar interiors and the analysis of exo-planetary systems have mutual benefits since not only they share similar techniques for obtaining the data (analysis of light curves) but also the high precision with which today asteroseismology can provide the global parameters of stars is crucial to accurately and precisely characterize the planetary systems. In this contribution I briefly describe this symbiosis.
