On turbulence driven by axial precession and tidal evolution of the spin-orbit angle of close-in giant planets
Adrian J. Barker
The spin axis of a rotationally deformed planet is forced to precess about its orbital angular momentum vector, due to the tidal gravity of its host star, if these directions are m…
Nonlinear tides in a homogeneous rotating planet or star: global simulations of the elliptical instability
Adrian J. Barker
I present results from the first global hydrodynamical simulations of the elliptical instability in a tidally deformed gaseous planet (or star) with a free surface. The elliptical…
Nonlinear tides in a homogeneous rotating planet or star: global modes and elliptical instability
Adrian J. Barker, Harry J. Braviner, Gordon I. Ogilvie
We revisit the global modes and instabilities of homogeneous rotating ellipsoidal fluid masses, which are the simplest global models of rotationally and tidally deformed gaseous pl…
Nonlinear hydrodynamical evolution of eccentric Keplerian discs in two dimensions: validation of secular theory
Adrian J. Barker, Gordon I. Ogilvie
We perform global two-dimensional hydrodynamical simulations of Keplerian discs with free eccentricity over thousands of orbital periods. Our aim is to determine the validity of se…
