Parametric instability in warped astrophysical discs: growth, saturation and feedback
Callum W. Fairbairn, Gordon I. Ogilvie
Attempts to understand the dynamics of warped astrophysical discs have garnered significant attention, largely motivated by the growing catalogue of observed distorted systems. Pre…
Tidally excited gravity waves in the cores of solar-type stars: resonances and critical-layer formation
Zhao Guo, Gordon I. Ogilvie, Adrian J. Barker
We simulate the propagation and dissipation of tidally induced nonlinear gravity waves in the cores of solar-type stars. We perform hydrodynamical simulations of a previously devel…
Standing solitary waves as transitions to spiral structures in gravitationally unstable accretion disks
Hongping Deng, Gordon I. Ogilvie
Astrophysical disks that are sufficiently cold and dense are linearly unstable to the formation of axisymmetric rings as a result of the disk's gravity. In practice, spiral structu…
Hydrodynamics of warps in the local model of astrophysical discs
Gordon I. Ogilvie
We show how the local approximation of astrophysical discs, which is the basis for the well known model of the shearing box, can be used to study many aspects of the dynamics of wa…
Nonlinear behaviour of warped discs around a central object with a quadrupole moment
Hongping Deng, Gordon Ogilvie
The nonlinear behaviour of low-viscosity warped discs is poorly understood. We verified a nonlinear bending-wave theory, in which fluid columns undergo affine transformations, with…
Planet-Disk Interactions
Sijme-Jan Paardekooper, Ruobing Dong, Paul Duffell +4
Planet-disk interactions, where an embedded massive body interacts gravitationally with the protoplanetary disk it was formed in, can play an important role in reshaping both the d…
