The characterization of exoplanets has been considerably improved during the last decade mainly through space missions (Kepler/K2, CoRoT) and also the characterization of their host stars by stellar seismology. Nowadays, TESS and CHEOPS are the only two important missions that will provide short-cadence high-precision photometric time-series for a large amount of targets. This project explored the asteroseismic potential of CHEOPS light-curves. For that purpose, we analysed the probability of detecting solar-like pulsations, and the accuracy we could obtain for estimates of the seismic indices for the expected targets, observing time and expected duty cycle of this mission. Our results suggested that we can determine the frequency at maximum power for evolved and/or massive F-G-K solar-like stars with an uncertainty better than 5%. Asteroseismology therefore enables us to decrease age, mass, radius and density uncertainties significantly in the characterization of exoplanet host stars.
