Disc tearing: numerical investigation of warped disc instability
Anagha Raj, Chris Nixon, Suzan Dogan
We present numerical simulations of misaligned discs around a spinning black hole covering a range of parameters. Previous simulations have shown that discs that are strongly warpe…
Instability of non-Keplerian warped discs
Suzan Dogan, Chris Nixon
Many accretion discs are thought to be warped. Recent hydrodynamical simulations show that (i) discs can break into distinct planes when the amplitude of an imposed warp is suffici…
Instability of warped discs
S. Doğan, C. J. Nixon, A. R. King +1
Accretion discs are generally warped. If a warp in a disc is too large, the disc can `break' apart into two or more distinct planes, with only tenuous connections between them. Fur…
Magnetic field gradient effects on the magnetorotational instability
Suzan Dogan
The magnetorotational instability (MRI), also known as the Balbus -- Hawley instability, is thought to have an important role on the initiation of turbulence and angular momentum t…
The Kozai-Lidov Mechanism in Hydrodynamical Disks
Rebecca G. Martin, Chris Nixon, Stephen H. Lubow +4
We use three dimensional hydrodynamical simulations to show that a highly misaligned accretion disk around one component of a binary system can exhibit global Kozai-Lidov cycles, w…
Ion-cyclotron Resonance with Streaming Bi-Maxwellian Distribution
S. Dogan, E. R. Pekunlu
We investigate the effect of bulk velocity of the solar wind on the propagation characteristics of ion-cyclotron waves (ICWs). Our model is based on the kinetic theory. We solve th…
