Rotational threshold in global numerical dynamo simulations
Martin Schrinner
Magnetic field observations of low-mass stars reveal an increase of magnetic activity with increasing rotation rate. The so-called activity-rotation relation is usually attributed…
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…
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…
Weak and Strong Field Dynamos: from the Earth to the stars
J. Morin, E. Dormy, M. Schrinner +1
Observations of magnetism in very low mass stars recently made important progress, revealing characteristics that are now to be understood in the framework of dynamo theory. In par…
Global dynamo models from direct numerical simulations and their mean-field counterparts
M. Schrinner
Context. The recently developed test-field method permits to compute dynamo coefficients from global, direct numerical simulations. The subsequent use of these parameters in mean-f…
