The core-mantle mode of gravitational oscillation
Mathieu Dumberry
We present the characteristics of a mode of axial oscillation between Earth's mantle, fluid core and solid inner core that has not been previously reported. The mode involves a qua…
Coupled orbital and interior structure evolution of lava planets
Mahesh Herath, Nicolas B. Cowan, Charles-Édouard Boukaré +1
Lava planets likely did not form in their current orbits, instead migrating inward via orbital decay, which influenced the evolution of their magma oceans. We introduce a coupled t…
The mantle-inner core gravitational mode of oscillation in a strong magnetic field regime
Mathieu Dumberry
The mantle-inner core gravitational (MICG) mode is the free mode axial oscillation between the mantle and inner core sustained by the gravitational torque between their degree 2 or…
Deviation of Mercury's spin axis from an exact Cassini state induced by dissipation
Ian MacPherson, Mathieu Dumberry
We compute predictions of the deviation of Mercury's spin axis from an exact Cassini state caused by tidal dissipation, and viscous and electromagnetic (EM) friction at the core-ma…
The Cassini State of the Moon's inner core
Christopher Stys, Mathieu Dumberry
We present a model of the precession dynamics of the Moon that comprises a fluid outer core and a solid inner core. We show that three Cassini states associated with the inner core…
A past lunar dynamo thermally driven by the precession of its inner core
Christopher Stys, Mathieu Dumberry
The Cassini state equilibrium associated with the precession of the Moon predicts that the mantle, fluid core and solid inner core precess at different angles. We present estimates…
Viscoelastic relaxation within the Moon and the phase lead of its Cassini state
Olivier Organowski, Mathieu Dumberry
Analyses of Lunar Laser Ranging data show that the spin-symmetry axis of the Moon is ahead of its expected Cassini state by an angle of = 0.27 arcsec. This indicates the pres…
Viscous dissipation in the fluid core of the Moon
Jiarui Zhang, Mathieu Dumberry
The spin axes of the mantle, fluid core and solid inner core of the Moon precess at frequency yr though with different orientations, leading to viscous frictio…
The influence of a fluid core and a solid inner core on the Cassini sate of Mercury
Mathieu Dumberry
We present a model of the Cassini state of Mercury that comprises an inner core, a fluid core and a mantle. Our model includes inertial and gravitational torques between interior r…
Influence of an inner core on the long-period forced librations of Mercury
Marie Yseboodt, Attilio Rivoldini, Tim Van Hoolst +1
The planetary perturbations on Mercury's orbit lead to long-period forced librations of Mercury's mantle. These librations have previously been studied for a planet with two layers…
