The Powers of 9 and Related Mathematical Tables from Babylon
Mathieu Ossendrijver
Late-Babylonian mathematics (450-100 BC), represented by some 60 cuneiform tablets from Babylon and Uruk, is incompletely known compared to its abundantly preserved, well-studied O…
Magnetoconvection and dynamo coefficients III: alpha-effect and magnetic pumping in the rapid rotation regime
P. J. Käpylä, M. J. Korpi, M. Ossendrijver +1
Aims. The alpha- and gamma-effects, which are responsible for the generation and turbulent pumping of large scale magnetic fields, respectively, due to passive advection by convect…
Do spherical alpha^2-dynamos oscillate?
G. Rüdiger, D. Elstner, M. Ossendrijver
The question is answered whether kinematic alpha^2-shell-dynamos are able to produce a cyclic activity or not. The alpha-effect is allowed to be latitudinally inhomogeneous and/or…
Magnetoconvection and dynamo coefficients: II. Field-direction dependent pumping of magnetic field
M. Ossendrijver, M. Stix, A. Brandenburg +1
We study the pumping of magnetic flux in three-dimensional compressible magnetoconvection in the context of stellar dynamos. The simulation domain represents a rectangular section…
Magnetoconvection and dynamo coefficients: Dependence of the alpha-effect on rotation and magnetic field
M. Ossendrijver, M. Stix, A. Brandenburg
We present numerical simulations of three-dimensional compressible magnetoconvection in a rotating rectangular box that represents a section of the solar convection zone. The box c…
Crisis-induced intermittency due to attractor-widening in a buoyancy-driven solar dynamo
Eurico Covas, Mathieu Ossendrijver
In a recent paper [M. A. J. H. Ossendrijver, A&A {\bf 359}, 364 (2000)] numerical simulations of a 2D mean--field model where shown to produce grand minima, typical of the long-ter…
