  Asteroseismology is among the most powerful observational tools to determine
fundamental properties of stars. Space-based photometry has recently enabled
the systematic detection of oscillations in exoplanet host stars, allowing a
combination of asteroseismology with transit and radial-velocity measurements
to characterize planetary systems. In this contribution I will review the key
synergies between asteroseismology and exoplanet science such as the precise
determination of radii and ages of exoplanet host stars, as well as
applications of asteroseismology to measure spin-orbit inclinations in
multiplanet systems and orbital eccentricities of small planets. Finally I will
give a brief outlook on asteroseismic studies of exoplanet hosts with current
and future space-based missions such as K2 and TESS.
