Motional induction in Ganymede's ocean
Simon Cabanes, Thomas Gastine, Alexandre Fournier
We investigate the magnetic signature of oceanic circulation in Ganymede's subsurface ocean using kinematic induction modeling. Our approach couples zonal jet flows from rotating t…
Rotating convection with a melting boundary: an application to the icy moons
T. Gastine, B. Favier
A better understanding of the ice-ocean couplings is required to better characterise the hydrosphere of the icy moons. Using global numerical simulations in spherical geometry, we…
Quasi-geostrophic convection-driven dynamos in a thick spherical shell
Olivier Barrois, Thomas Gastine, Christopher C. Finlay
We present dynamos computed using a hybrid QG-3D numerical scheme in a thick spherical shell geometry. Our model is based on a quasi-geostrophic convection code extended with a 3D…
Comparison of Quasi-Geostrophic, Hybrid and 3D models of planetary core convection
Olivier Barrois, Thomas Gastine, Christopher C. Finlay
We present investigations of rapidly-rotating convection in a thick spherical shell geometry relevant to planetary cores, comparing results from Quasi-Geostrophic, 3D and hybrid QG…
Transition from multipolar to dipolar dynamos in stratified systems
B. Zaire, L. Jouve, T. Gastine +4
Observations of surface magnetic fields of cool stars reveal a large diversity of configurations. Although there is now a consensus that these fields are generated through dynamo p…
An assessment of implicit-explicit time integrators for the pseudo-spectral approximation of Boussinesq thermal convection in an annulus
V. Gopinath, A. Fournier, T. Gastine
We analyze the behaviour of an ensemble of time integrators applied to the semi-discrete problem resulting from the spectral discretization of the equations describing Boussinesq c…
