Hemispherical Parker waves driven by thermal shear in planetary dynamos
Wieland Dietrich, Dieter Schmitt, Johannes Wicht
Planetary and stellar magnetic fields are thought to be sustained by helical motions (-effect) and, if present, differential rotation (-effect). In the Sun, the strong differ…
A domino model for geomagnetic field reversals
N. Mori, D. Schmitt, A. Ferriz-Mas +4
We solve the equations of motion of a one-dimensional planar Heisenberg (or Vaks-Larkin) model consisting of a system of interacting macro-spins aligned along a ring. Each spin has…
Coupled spin models for magnetic variation of planets and stars
A. Nakamichi, H. Mouri, D. Schmitt +3
Geomagnetism is characterized by intermittent polarity reversals and rapid fluctuations. We have recently proposed a coupled macro-spin model to describe these dynamics based on th…
Mode analysis of numerical geodynamo models
Martin Schrinner, Dieter Schmitt, Peter Hoyng
It has been suggested in Hoyng (2009) that dynamo action can be analysed by expansion of the magnetic field into dynamo modes and statistical evaluation of the mode coefficients. W…
The initial temporal evolution of a feedback dynamo for Mercury
D. Heyner, D. Schmitt, J. Wicht +3
Various possibilities are currently under discussion to explain the observed weakness of the intrinsic magnetic field of planet Mercury. One of the possible dynamo scenarios is a d…
Saturation and time dependence of geodynamo models
M. Schrinner, D. Schmitt, R. Cameron +1
In this study we address the question under which conditions a saturated velocity field stemming from geodynamo simulations leads to an exponential growth of the magnetic field in…
