Warped discs and the directional stability of jets in Active Galactic Nuclei
Priyamvada Natarajan, Philip J. Armitage
Warped accretion discs in Active Galactic Nuclei (AGN) exert a torque on the black hole that tends to align the rotation axis with the angular momentum of the outer disc. We comput…
Accretion Disc Evolution in Single and Binary T Tauri Stars
Philip J. Armitage, C. J. Clarke, C. A. Tout
We present theoretical models for the evolution of T Tauri stars surrounded by circumstellar discs. The models include the effects of pre-main-sequence stellar and time dependent d…
Tilted accretion discs in cataclysmic variables: tidal instabilities and superhumps
J. R. Murray, P. J. Armitage
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 d…
The effects of tidally induced disc structure on white dwarf accretion in intermediate polars
J. R. Murray, P. J. Armitage, L. Ferrario +1
We investigate the effects of tidally induced asymmetric disc structure on accretion onto the white dwarf in intermediate polars. Using numerical simulation, we show that it is pos…
Simulations of spiral structure in the accretion disc of IP Pegasi during outburst
P. J. Armitage, J. R. Murray
We consider the implications of the detection of spiral structure in the accretion disc of the binary IP Pegasi. We use numerical simulations of the development of a disc outburst…
