A biased review of work on the interaction between a tidal stream and an accretion disk in binary systems.

For a more complete review, see Livio (1993).

Observations

cataclysmic variables: asymmetric light curves, "flickering" , Doppler Tomography

low-mass X-ray binaries: lack of eclipses, "dipping"

Theory

Roche lobe overflow, ballistic stream

Simulations

from 1975(!) to the present
