Nonlinear hydrodynamical evolution of eccentric Keplerian discs in two dimensions: validation of secular theory
(Oxford University PressMonthly Notices of the Royal Astronomical Society, 2016-03-11)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 secular theory in describing the evolution ...

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 ...

Tidal interactions between planets and stars
(University of CambridgeDepartment of Applied Mathematics and Theoretical PhysicsSelwyn College, 2011-06-07)Since the first discovery of an extrasolar planet around a solar-type star, observers have detected over 500 planets outside the solar system. Many of these planets have Jovian masses and orbit their host stars in orbits ...
