Abstract Resolved observations are bringing new constraints on the origin of radial gaps in protoplanetary disks. The kinematics, sampled in detail in one case-study, are indicative of non-Keplerian…

THE KOZAI–LIDOV MECHANISM IN HYDRODYNAMICAL DISKS

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, where the…

Hydrodynamic Torques in Circumbinary Accretion Disks

Gaseous disks have been proposed as a mechanism for facilitating mergers of binary black holes. We explore circumbinary disk systems to determine the evolution of the central binary. To do so, we…

RINGED ACCRETION DISKS: INSTABILITIES

We analyze the possibility that several instability points may be formed, due to the Paczyński mechanism of violation of mechanical equilibrium, in the orbiting matter around a supermassive Kerr…

Evolution of warped and twisted accretion discs in close binary systems

Context. There are numerous examples of accretion discs in binary sys tems where the disc midplane is believed to be inclined relat iv to the binary orbit plane. Aims. We aim to examine the detailed…

THE EVOLUTION OF A SUPERMASSIVE BINARY CAUSED BY AN ACCRETION DISC

The interaction between a massive binary and a non-self-gravitating circumbinary accretion disc is considered. The shape of the stationary twisted disc produced by the binary is calculated. It is…

Observational implications of precessing protostellar discs and jets

We consider the dynamics of a protostellar disc in a binary system where the disc is misaligned with the orbital plane of the binary, with the aim of determining the observational consequences for…

Black hole mergers: can gas discs solve the ‘final parsec’ problem?

We compute the effect of an orbiting gas disc in promoting the coalescence of a central supermassive black hole binary. Unlike earlier studies, we consider a finite mass of gas with explicit time…

The observable effects of tidally induced warps in protostellar discs

We consider the response of a protostellar disc to a tidally induced warp and the resultant changes in the spectral energy distribution (SED). We argue that for typical protostellar disc parameters…

Broken discs: Warp propagation in accretion discs

Simulation of the viscous evolution of an accretion disc around a spinning black hole finds that non-linear fluid effects, which reduce the effective viscosities in warped regions, can promote breaking of the disc into two distinct planes.

Accretion disc viscosity: how big is alpha?

We consider observational and theoretical estimates of the accretion disc viscosity parameter a. We find that in thin, fully ionized discs, the best observational evidence suggests a typical range a…

The tidally induced warping, precession and truncation of accretion discs

We present the results of non linear, hydrodynamic simulations, in three dimensions, of the tidal perturbation of accretion discs in binary systems where the orbit is circular and not necessarily…

We consider the dynamics of a protostellar disk surrounding a star in a circular-orbit binary system. Our aim is to determine whether, if the disk is initially tilted with respect to the plane of the…
