The asteroseismology program of the NASA Kepler Mission is not only
determining the properties and internal structures of exoplanet-host
stars (see talk of Chaplin, this seminar), it is providing seismic
data of unprecedented quality and duration for the seismic study of
many different types of stars, in various evolutionary stages. We
highlight the most important achievements of the mission so far, in
particular results on young stars considerably more massive than the
Sun, red giants and supergiants, and compact stars. Of particular
importance for tuning evolutionary models are the pulsating stars of
various classes that Kepler has discovered to occur in eclipsing
binaries or in clusters. We illustrate the level of improvement
provided by the Kepler data combined with ground-based spectroscopy,
for seismic inferences on stellar structure. An extrapolation of the
present data sets to those which will have been assembled by the end
of the mission is used to predict the very stringent constraints we
will have on single and binary star evolution.
