Observation of the variations in the Earth's rotation at time scales ranging from subdiurnal to
multidecadal allows us to learn about its deep interior structure. We review all three types of …

Abstract Changes in the Earth's rotation are deeply connected to fluid dynamical processes
in the outer core. This connection can be explored by studying the associated Earth …

The Earth tides are the motions induced in the solid Earth, and the changes in its
gravitational potential, induced by the tidal forces from external bodies.(These forces, acting …

One hundred and twenty years after the first detection of a remote seismic event by Von
Rebeur-Paschwitz (1889) and 60 years after the elaboration of complete mean seismic …

The rotation of Mercury is presently captured in a 3/2 spin–orbit resonance with the orbital
mean motion. The capture mechanism is well understood as the result of tidal interactions …

We present an inversion of nutation observations in terms of parameters characterizing the
Earth's interior properties. We use a Bayesian inversion in the time-domain, allowing us to …

The gravitational torque applied on the Earth by the other celestial bodies generates
periodic variations in the orientation of the Earth's rotation axis in space which are called …

The Earth's spin axis is inclined by∊= 23.4° with respect to the ecliptic normal and precesses
in space with a period of 26 kyr. The fluid core and solid inner core precess at slightly …

Dissipative core—mantle coupling is evident in observations of the Earth's nutations,
although the source of this coupling is uncertain. Magnetic coupling occurs when conducting …

Interactions between the core and the mantle arise when heat, mass, momentum, or charge
is transferred across the core-mantle boundary (CMB). Each of these interactions has …
