Asteroseismology of Exoplanets-host-Stars

Abstract: More than 500 planets are presently known to orbit around stars other than the Sun. The characterization of these planetary systems need a precise determination of the parameters of the central stars (masses, radii, ages, abundances, etc.). Meanwhile the characteristics of stars with detected planets and stars for which not planet has yet been observed may give some hints about planetary formation and migration. In this framework, asteroseismology represents an important tool which may lead to precisions never reached before. I will discuss the present situation about asteroseismology of exoplanets-host stars, the obtained results and the future prospects.
