The dynamics of twisted disc formed after the tidal disruption of a star by a rotating black hole
P. B. Ivanov, V. V. Zhuravlev, J. C. B. Papaloizou
We consider misaligned accretion discs formed after tidal disruption events occurring when a star encounters a supermassive rotating black hole. We use the linear theory of warped…
Subcritical transition to turbulence in accretion disc boundary layer
V. V. Zhuravlev, D. N. Razdoburdin
Enhanced angular momentum transfer through the boundary layer near the surface of weakly magnetised accreting star is required in order to explain the observed accretion timescales…
Transient growth of perturbations on scales beyond the accretion disc thickness
D. N. Razdoburdin, V. V. Zhuravlev
Turbulent state of spectrally stable shear flows may be developed and sustained according to the bypass scenario of transition. If it works in non-magnetised boundless and homogene…
Transient dynamics of perturbations in astrophysical disks
Dmitry N. Razdoburdin, Viacheslav V. Zhuravlev
This paper reviews some aspects of one of the major unsolved problems in understanding astrophysical (in particular, accretion) disks: whether the disk interiors may be effectively…
No Evidence for Bardeen-Petterson Alignment in GRMHD Simulations and Semi-Analytic Models of Moderately Thin, Prograde, Tilted Accretion Disks
Viacheslav V. Zhuravlev, Pavel B. Ivanov, P. Chris Fragile +1
In this paper we introduce the first results that use data extracted directly from numerical simulations as inputs to the analytic twisted disk model of Zhuravlev & Ivanov. In both…
Conservative GRMHD Simulations of Moderately Thin, Tilted Accretion Disks
Danilo Morales Teixeira, P. Chris Fragile, Viacheslav V. Zhuravlev +1
This paper presents our latest numerical simulations of accretion disks that are misaligned with respect to the rotation axis of a Kerr black hole. In this work we use a new, fully…
