Spiral waves in accretion discs - theory
Henri M. J. Boffin
Spirals shocks have been widely studied in the context of galactic dynamics and protostellar discs. They may however also play an important role in some classes of close binary sta…
Direct Monte Carlo simulations of accretion discs
Takuya Matsuda, Hiromi Mizutani, Henri M. J. Boffin
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 b…
High resolution simulations of star formation
Henri M. J. Boffin, Neil Francis, Anthony P. Whitworth
In order to study the capabilities of SPH in self-gravitating hydrodynamical problems, we have performed a series of three-dimensional numerical simulations of the collapse of a ro…
Spiral waves in accretion discs
H. M. J. Boffin, D. Steeghs
In the first part of this article, we review the observational evidence for spirals in the accretion discs of cataclysmic variables. It is shown that with the increasing amount of…
