An S-curve like hysteresis relation between temperature and surface density is the basis for thelimit cycle model of these objects. That model was first introduced to explain these objects in a subsetof cataclysmic variables also known as U Geminorum stars. Balbus and Hawley showed that theonset of turbulence in these objects could be caused by the magnetorotational instability. Amagnetized one of these was first proposed by Lynden-Bell and is the subject of theBlandford-Znajek process. Most models of them are based on the Shakura-Sunyaevalpha-prescription for anomalous stress. One of these is thought to (*) surround a supermassive blackhole in quasars, and they can result from objects straying inside the Roche limit.
