Conclusion/ExtensionsInteractions between small-scale waves and the media through which they propagate can have large-scale dynamical consequences in a variety of astrophysical systems
•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
