We propose a new synergic strategy that merges the potential of asteroseismology with solar space climate techniques in order to characterize solar-like stars and their interaction with hosted exoplanets. The method is based on the use of seismic data obtained by the space missions Kepler/K2 or TESS Transiting Exoplanet Survey Satellite, coupled with stellar activity estimates deduced from ground-based campaigns.
Our investigation allows us to obtain not only a highly accurate characterization of the mother star and its orbiting planet, but also to study the stellar magnetic activity and the star-planet interaction in analogy to the Sun-Earth system allowing to determine the extension of the exoplanetary magnetosphere and the values of stellar wind dynamic pressure. This information, coupled with
the precise age estimation by asteroseismology, will allow determining how long
an atmosphere could resist to the action of stellar wind enabling to directly quantify the portion of the
atmosphere which could potentially be eroded.
