Magnetic effects on fields morphologies and reversals in geodynamo simulations
Mélissa D. Menu, Ludovic Petitdemange, Sébastien Galtier
The dynamo effect is the most popular candidate to explain the non-primordial magnetic fields of astrophysical objects. Although many systematic studies of parameters have already…
Magnetohydrodynamics of stably stratified regions in planets and stars
J. Philidet, C. Gissinger, F. Lignières +1
Stably stratified layers are present in stellar interiors (radiative zones) as well as planetary interiors - recent observations and theoretical studies of the Earth's magnetic fie…
Inverse cascade of hybrid helicity in -MHD turbulence
Mélissa D. Menu, Sébastien Galtier, Ludovic Petitdemange
We investigate the impact of a solid-body rotation on the large-scale dynamics of an incompressible magnetohydrodynamic turbulent flow in presence of a background magnetic fi…
A magnetically driven equatorial jet in Europa's ocean
Christophe Gissinger, Ludovic Petitdemange
During recent decades, data from space missions have provided strong evidence of deep liquid oceans underneath a thin outer icy crust on several moons of Jupiter, particularly Euro…
Systematic parameter study of dynamo bifurcations in geodynamo simulations
Ludovic Petitdemange
We investigate the nature of the dynamo bifurcation in a configuration applicable to the Earth's liquid outer core. Numerical studies on the stability domain of dipolar magnetic fi…
