Earth's rotation: observations and relation to deep interior
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 …

Identification of inertial modes in the solar convection zone
The observation of global acoustic waves (p modes) in the Sun has been key to unveiling its
internal structure and dynamics. A different kind of wave, known as sectoral Rossby modes …

Internal energy dissipation in Enceladus's subsurface ocean from tides and libration and the role of inertial waves
Enceladus is characterized by a south polar hot spot associated with a large outflow of heat,
the source of which remains unclear. We compute the heat generated via viscous …

Core eigenmodes and their impact on the Earth's rotation
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 viscous and Ohmic damping of the Earth's free core nutation
The cause for the damping of the Earth's free core nutation (FCN) and the free inner core
nutation eigenmodes has been a matter of debate since the earliest reliable estimations …
