Tilted accretion discs in cataclysmic variables : Tidal instabilities and superhumps
We investigate the growth of tidal instabilities in accretion discs in a binary star potential, using three dimensional numerical simulations. As expected from analytic work, the disc is prone to an eccentric instability provided that it is large enough to extend to the 3:1 resonance. The eccentric disc leads to positive superhumps in the light curve. It has been proposed that negative superhum...
متن کاملAtlas of Tilted Accretion Discs & Source to Negative Superhumps
Using smoothed particle hydrodynamics, we numerically simulate steady state accretion discs for Cataclysmic Variable Dwarf Novae systems that have a secondaryto-primary mass ratio 0.35 ≤ q ≤ 0.55. After these accretion discs have come to quasi-equilibrium, we rotate each disc out of the orbital plane by δ = (1, 2, 3, 4, 5, or 20)o to induce negative superhumps. For accretion discs tilted 5o, we...
متن کاملThree-dimensional Sph Simulations of Accretion Discs *
We discuss some 3D numerical simulations of accretion discs using the SPH method and a polytropic equation of state. We show that discs exist even for as large value of the polytropic index as 1.2, and that these discs are always in hydrostatic balance. We also show that even without any inflow, spiral shocks appear in the discs.
متن کاملDirect Monte Carlo simulations of accretion discs
We apply the Direct Simulation Monte Carlo (DSMC) method, developed originally to calculate rarefied gas dynamical problems, to study the gas flow in an accretion disc in a close binary system. The method involves viscosity and thermal conduction automatically, and can thus simulate turbulent viscosity (α viscosity).
متن کاملModelling magnetised accretion discs
Some recent results are reviewed that lead us now to believe that accretion discs are basically always magnetised. The main components are Balbus-Hawley and Parker instabilities on the one hand and a dynamo process on the other. A mechanical model for the Balbus-Hawley instability is presented and analysed quantitatively. Three-dimensional simulations are discussed, especially the resulting mag...
