Quasi-periodic oscillations and the global modes of relativistic, MHD accretion discs
The high-frequency quasi-periodic oscillations (HFQPOs) that punctuate the light curves of X-ray binary systems present a window onto the intrinsic properties of stellar-mass black holes and hence a testbed for general ...
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 ...
