"The Disk Instability Model (DIM)"

Abstract:
The Disk Instability Model (DIM) has become the general accepted explanation for dwarf nova outbursts observed in many CVs and is regarded as the accretion disc model which has linked the theory of accretion discs to observations most successfully. In spite of its success, the DIM is facing some serious difficulties.

I'll confront state of the art calculations including recently developed extensions such as mass transfer variations, irradiation, and stream impact heating, with observations of dwarf novae. Finally, constraints on future versions of the model will be discussed.
