Because of gravitational interactions with their companions, the rotational dynamics of
planets and stars involve periodic perturbations of their shape, the direction of their …

Tidal dissipation in star–planet systems can occur through various mechanisms, among
which is the elliptical instability. This acts on elliptically deformed equilibrium tidal flows in …

Planets and satellites can undergo physical librations, which consist of forced periodic
variations in their rotation rate induced by gravitational interactions with nearby bodies. This …

In this paper, we present an experimental investigation of the turbulent saturation of the flow
driven by the parametric resonance of inertial waves in a rotating fluid. In our set-up, a half …

Tidally distorted rotating stars and gaseous planets are subject to a well-known linear fluid
instability–the elliptical instability. It has been proposed that this instability might drive …

Large-scale planetary or stellar magnetic fields generated by a dynamo effect are mostly
attributed to flows forced by buoyancy forces in electrically conducting fluid layers. However …

Internal shear layers generated by the longitudinal libration of the inner core in a spherical
shell rotating at a rate for the amplitudes of the main and secondary beams, respectively, are …

Context. Surface magnetic fields have been detected in 5–10% of isolated massive stars,
hosting outer radiative envelopes. They are often thought to have a fossil origin, resulting …

Longitudinal libration corresponds to the periodic oscillation of a body's rotation rate and is,
along with precessional and tidal forcings, a possible source of mechanically-driven …

The process by which the subsurface ocean on Enceladus is heated remains a puzzle. Tidal
interaction with Saturn and Dione is the leading candidate but whether the dominant heating …
