  Asteroseismic investigations, particularly based on data on stellar
oscillations from the CoRoT and Kepler space missions, are providing unique
possibilities for investigating the properties of stellar interiors. This
constitutes entirely new ways to study the effects of dynamic phenomena on
stellar structure and evolution. Important examples are the extent of
convection zones and the associated mixing and the direct and indirect effects
of stellar rotation. In addition, the stellar oscillations themselves show very
interesting dynamic behaviour. Here we discuss examples of the results obtained
from such investigations, across the Hertzsprung-Russell diagram.
