Conclusion/Extensions Interactions between small-scale waves and the media through which they propagate can have large-scale dynamical consequences in a variety of astrophysical systems Some examples/possibilities: • Wave-dominated flows – winds from cool evolved stars • Radiative amplification of acoustic/Alfvén waves in hot star winds • Accretion-generated Alfvén/gravity waves in pre-MS objects • Internal excitation of gravity modes by planetary companions • Alfvén waves from satellite-planet, planet-star interactions
