Hydrodynamic instability in eccentric astrophysical discs
Adrian J. Barker, Gordon I. Ogilvie
Eccentric Keplerian discs are believed to be unstable to three-dimensional hydrodynamical instabilities driven by the time-dependence of fluid properties around an orbit. These ins…
Local and global dynamics of eccentric astrophysical discs
Gordon I. Ogilvie, Adrian J. Barker
We formulate a local dynamical model of an eccentric disc in which the dominant motion consists of elliptical Keplerian orbits. The model is a generalization of the well known shea…
Theory and simulations of rotating convection
Adrian J. Barker, Adam M. Dempsey, Yoram Lithwick
We study thermal convection in a rotating fluid in order to better understand the properties of convection zones in rotating stars and planets. We first derive mixing-length theory…
Nonlinear evolution of tidally forced inertial waves in rotating fluid bodies
B. Favier, A. J. Barker, C. Baruteau +1
We perform one of the first studies into the nonlinear evolution of tidally excited inertial waves in a uniformly rotating fluid body, exploring a simplified model of the fluid env…
