The outbursts of dwarf novae.

Truss, M. R. and Murray, J. R. and Wynn, J. R. and Edgar, R.G. (2000) 'The outbursts of dwarf novae.', Monthly notices of the Royal Astronomical Society., 319 (2). pp. 467-476.


We present a numerical scheme for the evolution of an accretion disc through a dwarf nova outburst. We introduce a time-varying artificial viscosity into an existing smoothed particle hydrodynamics code optimized for two- and three-dimensional simulations of accretion discs. The technique gives rise to coherent outbursts and can easily be adapted to include a complete treatment of thermodynamics. We apply a two-dimensional isothermal scheme to the system SS Cygni, and present a wide range of observationally testable results.
