Stability of accretion discs threaded by a strong magnetic field
R. Stehle, H. C. Spruit
We study the stability of poloidal magnetic fields anchored in a thin accretion disc. The two-dimensional hydrodynamics in the disc plane is followed by a grid-based numerical simu…
The standstill luminosity in Z Cam systems
R. Stehle, A. King, C. Rudge
We consider accretion discs in close binary systems. We show that heating of a disc at the impact point of the accretion stream contributes significantly to the local energy budget…
A mystery solved: the mass ratio of the dwarf nova EM Cygni
R. C. North, T. R. Marsh, C. K. J. Moran +3
We have discovered that the spectrum of the well-known dwarf nova EM Cyg is contaminated by light from a K2-5V star (in addition to the K-type mass donor star). The K2-5V star cont…
On the observability of spiral structures in CV accretion discs
Danny Steeghs, Rudolf Stehle
We use the grid of hydrodynamic accretion disc calculations of Stehle (1999) to construct orbital phase dependent emission line profiles of thin discs carrying spiral density waves…
Structure and properties of transition fronts in accretion discs
Kristen Menou, Jean-Marie Hameury, Rudolf Stehle
We use high-resolution time-dependent numerical simulations of accretion discs around white dwarfs to study the structure and properties of transition fronts in the context of the…
Interchange instability in an accretion disc with a poloidal magnetic field
H. C. Spruit, R. Stehle, J. C. B. Papaloizou
We investigate the stability to nonaxisymmetric perturbations of an accretion disc in which a poloidal magnetic field provides part of the radial support against gravity. Interchan…
