▪ Abstract In this review we describe the discovery and development of understanding of the
so-called elliptical instability. This is the name given to the linear instability mechanism that …

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 …

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 …

In this article, the multipolar vortex instability of the flow in a finite cylinder is addressed. The
experimental study uses a rotating elastic deformable tube filled with water which is …

In this review, we describe the physical processes driving the dynamical evolution of binary
stars, namely the circularization of the orbit and the synchronization of their spin and orbital …

The full non-linear evolution of the tidal instability is studied numerically in an ellipsoidal
fluid domain relevant for planetary cores applications. Our numerical model, based on a …

A theoretical and experimental study of the spin-over mode induced by the elliptical
instability of a flow contained in a slightly deformed rotating spherical shell is presented. This …

We first show that 7 out of the 20 giant impact basins of Mars recently reported by Frey [Frey,
H., 2008. Geophys. Res. Lett. 35. L13203] trace a great circle on Mars. The other five basins …

The nonlinear dynamics exhibited by a planar layer of precessing fluid is examined as a
canonical example of a strained rotating flow. The simple basic flow, Ubasic=− YXˆ+(X− 2εZ) …

We propose a causal relationship between the creation of the giant impact basins on Mars
by a large asteroid, ruptured when it entered the Roche limit, and the excitation of the …
