Tilted, warped, and eccentric disks
P. Chris Fragile, Adam Ingram, Gibwa Musoke +1
We review some of the interesting consequences that tilts, warps, and eccentricities can introduce into the dynamics, thermodynamics, and observational appearance of accreting syst…
Disc breaking and parametric instability in warped accretion discs
Loren E Held, Gordon I. Ogilvie
We present the first local simulations of disc breaking/tearing in a warped accretion disc. Warps can arise due to a misalignment between the disc and the rotation axis of the cent…
Instability and vertical eccentricity variation in global hydrodynamic disk simulations
Janosz W. Dewberry, Henrik N. Latter, Gordon I. Ogilvie +1
Many dynamical interactions can induce eccentricities in astrophysical accretion disks. Disk eccentricities in turn seed a variety of instabilities, even in ideal hydrodynamics. We…
Non-linear spiral waves in accretion discs
Joshua J. Brown, Gordon I. Ogilvie
We derive a simple, accurate, non-linear, global equation governing spiral density waves in thin, non-self-gravitating, inviscid accretion discs. These discs may have any slowly va…
High-resolution models of the vertical shear instability
Geoffroy Lesur, Henrik N. Latter, Gordon I. Ogilvie
(abridged) Context: The vertical shear instability (VSI) is a promising mechanism to generate turbulence and transport angular momentum in protoplanetary discs. While most recent w…
The Laplace Surface of a Circumplanetary Disc
Stephen H. Lubow, Gordon I. Ogilvie
The classical Laplace surface defines the location of circular particle orbits that do not undergo nodal precession around a planet with some obliquity. Close to the planet the sur…
