Mechanisms of Planetary and Stellar Dynamos
Emmanuel Dormy, Ludovic Petitdemange, Martin Schrinner
We review some of the recent progress on modeling planetary and stellar dynamos. Particular attention is given to the dynamo mechanisms and the resulting properties of the field. W…
Revisiting the ABC flow dynamo
Ismaël Bouya, Emmanuel Dormy
The ABC flow is a prototype for fast dynamo action, essential to the origin of magnetic field in large astrophysical objects. Probably the most studied configuration is the classic…
Bistability between equatorial and axial dipoles during magnetic field reversals
Christophe Gissinger, Ludovic Petitdemange, Martin Schrinner +1
Numerical simulations of the geodynamo in presence of an heterogeneous heating are presented. We study the dynamics and the structure of the magnetic field when the equatorial symm…
Dipole Collapse and Dynamo Waves in Global Direct Numerical Simulations
Martin Schrinner, Ludovic Petitdemange, Emmanuel Dormy
Magnetic fields of low-mass stars and planets are thought to originate from self-excited dynamo action in their convective interiors. Observations reveal a variety of field topolog…
