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 ...

Torsional Alfvén resonances as an efficient damping mechanism for non-radial oscillations in red giant stars
(Oxford University PressMonthly Notices of the Royal Astronomical Society, 2017-06-01)Stars are self-gravitating fluids in which pressure, buoyancy, rotation and magnetic fields provide the restoring forces for global modes of oscillation. Pressure and buoyancy energetically dominate, while rotation and ...
