Dynamical tides in exoplanetary systems containing hot Jupiters: Confronting theory and observations
(Oxford University PressMonthly Notices of the Royal Astronomical Society, 2017-09-11)We study the effect of dynamical tides associated with the excitation of gravity waves in an interior radiative region of the central star on orbital evolution in observed systems containing hot Jupiters. We consider ...

Nonlinear tides in a homogeneous rotating planet or star: global modes and elliptical instability
(Oxford University PressMonthly Notices of the Royal Astronomical Society, 2016-03-28)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 planets or stars. The tidal flow in a ...

Nonlinear tides in a homogeneous rotating planet or star: global simulations of the elliptical instability
(Oxford University PressMonthly Notices of the Royal Astronomical Society, 2016)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 instability is potentially important for ...

On turbulence driven by axial precession and tidal evolution of the spin–orbit angle of close-in giant planets
(Oxford University PressMonthly Notices of the Royal Astronomical Society, 2016-05-16)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 misaligned. This induces internal fluid ...
