Hydrodynamical models of accretion disks in SU UMa systems

We numerically test the mode-coupling model (Lubow 1991a) of tidal instabil ity in SU UMa systems. So far, all numerical models confirming it have been based on SPH codes and isothermal equation of state. In our paper we prese nt Eulerian models, using both isothermal approximation and the full energy equation. We also investigate influence of different ways of mass transfer . While isothermal models behave similarly to SPH simulations, the behavior of models with full energy equation is quite different, and the mode-coupl ing model is not confirmed in this case.
