Interplay between geostrophic vortices and inertial waves in precession-driven turbulence
F. Pizzi, G. Mamatsashvili, A. J. Barker +2
The properties of rotating turbulence driven by precession are studied using direct numerical simulations and analysis of the underlying dynamical processes in Fourier space. The s…
Tidally excited gravity waves in the cores of solar-type stars: resonances and critical-layer formation
Zhao Guo, Gordon I. Ogilvie, Adrian J. Barker
We simulate the propagation and dissipation of tidally induced nonlinear gravity waves in the cores of solar-type stars. We perform hydrodynamical simulations of a previously devel…
The effects of nonlinearities on tidal flows in the convective envelopes of rotating stars and planets in exoplanetary systems
A. Astoul, A. J. Barker
In close exoplanetary systems, tidal interactions drive orbital and spin evolution of planets and stars over long timescales. Tidally-forced inertial waves (restored by the Corioli…
A search for transit timing variations in the HATS-18 planetary system
John Southworth, A. J. Barker, T. C. Hinse +23
HATS-18b is a transiting planet with a large mass and a short orbital period, and is one of the best candidates for the detection of orbital decay induced by tidal effects. We pres…
Tidal dissipation due to inertial waves can explain the circularization periods of solar-type binaries
Adrian J. Barker
Tidal dissipation is responsible for circularizing the orbits and synchronizing the spins of solar-type close binary stars, but the mechanisms responsible are not fully understood.…
Nonlinear tidal excitation of super-harmonic gravity waves in main-sequence stars in binary and exoplanetary systems
P. B. Ivanov, S. V. Chernov, A. J. Barker
We study the role of nonlinear effects on tidally-excited internal gravity waves in stellar radiation zones in exoplanetary or binary systems. We are partly motivated to study tide…
