Earth's magnetic field is generated by fluid motions in the outer core. This geodynamo has
operated for over 3.4 billion years. However, the mechanism that has sustained the …

Astrophysical fluid bodies that orbit close to one another induce tidal distortions and flows
that are subject to dissipative processes. The spin and orbital motions undergo a coupled …

We propose that the recently observed quasi-periodic eruptions (QPEs) in galactic nuclei
are produced by unstable mass transfer due to Roche lobe overflow of a low-mass main …

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

The origin of lunar magnetic anomalies,,,, remains unresolved after their discovery more
than four decades ago. A commonly invoked hypothesis is that the Moon might once have …

We study the excitation and damping of tides in close binary systems, accounting for the
leading-order nonlinear corrections to linear tidal theory. These nonlinear corrections …

The Earth is a thermal engine generating the fundamental processes of geomagnetic field,
plate tectonics and volcanism. Large amounts of heat are permanently lost at the surface …

We perform one of the first studies into the non-linear evolution of tidally excited inertial
waves in a uniformly rotating fluid body, exploring a simplified model of the fluid envelope of …

Context. Since 1995, more than 500 extrasolar planets have been discovered orbiting very
close to their parent star, where they experience strong tidal interactions. Their orbital …

The combination of elliptical deformation of streamlines and vorticity can lead to the
destabilization of any rotating flow via the elliptical instability. Such a mechanism has been …
