The influence of a stably stratified layer on the hydromagnetic waves in the Earth's core and their electromagnetic torques
Fleur Seuren, Santiago A. Triana, Jérémy Rekier +2
Evidence from seismic studies, mineral physics, thermal evolution models and geomagnetic observations is inconclusive about the presence of a stably stratified layer at the top of…
Nutation Damping from Core-Mantle Boundary Topography
J. Rekier, S. A. Triana, A. Barik +2
Periodic gravitational forcing by the Moon and Sun produces small oscillations in Earth's rotation known as nutations. Nutations are amplified by a resonance with a natural motion…
Effects of the librationally induced flow in Mercury's fluid core with an outer stably stratified layer
Fleur Seuren, Santiago A. Triana, Jérémy Rekier +2
Observational constraints on Mercury's thermal evolution and magnetic field indicate that the top part of the fluid core is stably stratified. Here we compute how a stable layer af…
Electric interface condition for sliding and viscous contacts
Jérémy Rekier, Santiago A. Triana, Antony Trinh +1
First principles of electromagnetism impose that the tangential electric field must be continuous at the interface between two media. The definition of the electric field depends o…
Free Core Nutation and its relation to the Spin-Over Mode
Jérémy Rekier
The time-varying response of the Earth's and other planets' rotation to external gravitational torques depends strongly on their internal structure. In particular, the existence of…
Identification of inertial modes in the solar convection zone
Santiago Andrés Triana, Gustavo Guerrero, Ankit Barik +1
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 mode…
Inertial modes of a freely rotating ellipsoidal planet and their relation to nutations
Jeremy Rekier, Santiago A. Triana, Antony Trinh +1
We compute the inertial modes of a freely rotating two-layer planetary model with an ellipsoidal inviscid fluid core and a perfectly rigid mantle. We present a method to derive ana…
Universality of the spherical collapse with respect to the matter type : the case of a barotropic fluid with linear equation of state
François Staelens, Jérémy Rekier, André Füzfa
We study the spherical collapse of an over-density of a barotropic fluid with linear equation of state in a cosmological background. Fully relativistic simulations are performed by…
The coupling between inertial and rotational eigenmodes in planets with liquid cores
Santiago Andres Triana, Jeremy Rekier, Antony Trinh +1
The Earth is a rapidly rotating body. The centrifugal pull makes its shape resemble a flattened ellipsoid and Coriolis forces support waves in its fluid core, known as inertial wav…
Inertial Modes in Near-Spherical Geometries
J. Rekier, A. Trinh, S. A. Triana +1
We propose a numerical method to compute the inertial modes of a container with near-spherical geometry based on the fully spectral discretisation of the angular and radial directi…
Internal energy dissipation in Enceladus's ocean from tides and libration and the role of inertial waves
J. Rekier, A. Trinh, S. A. Triana +1
Enceladus is characterised by a south polar hot spot associated with a large outflow of heat, the source of which remains unclear. We compute the viscous dissipation resulting from…
Non-linear cosmological collapse of quintessence
Jeremy Rekier, Andre Fuzfa, Isabel Cordero-Carrion
We present a study of the fully relativistic spherical collapse in presence of quintessence using on Numerical Relativity, following the method proposed by the authors in a previou…
Fully relativistic nonlinear cosmological evolution in spherical symmetry using the BSSN formalism
Jeremy Rekier, Isabel Cordero-Carrion, Andre Fuzfa
We present a fully relativistic numerical method for the study of cosmological problems using the Baumgarte-Shapiro-Shibata-Nakamura formalism on a dynamical Friedmann-Lemaître-Rob…
Updated Constraints on Large Field Hybrid Inflation
Sebastien Clesse, Jeremy Rekier
We revisit the status of hybrid inflation in the light of Planck and recent BICEP2 results, taking care of possible transient violations of the slow-roll conditions as the field pa…
Cosmic acceleration with cosmological soft phonons in a network of large structures
J. Rekier, A. Füzfa
The dark energy scalar field is here presented as a mean-field effect arising from the collective motion of interacting structures on an expanding lattice. This cosmological analog…
