The excitation of spiral density waves through turbulent fluctuations in accretion discs II: Numerical Simulations with MRI driven turbulence
T. Heinemann, J. C. B. Papaloizou
We present fully three-dimensional local MRI simulations with the object of studying the excitation of non-axisymmetric spiral density waves that are observed to always be present…
The excitation of spiral density waves through turbulent fluctuations in accretion discs I: WKBJ theory
T. Heinemann, J. C. B. Papaloizou
We study and elucidate the mechanism of spiral density wave excitation in a differentially rotating turbulent flow. We formulate a set of wave equations with sources that are only…
Large-Scale Magnetic-Field Generation by Randomly Forced Shearing Waves
T. Heinemann, J. C. McWilliams, A. A. Schekochihin
A rigorous theory for the generation of a large-scale magnetic field by random non-helically forced motions of a conducting fluid combined with a linear shear is presented in the a…
Numerical experiments on dynamo action in sheared and rotating turbulence
T. A. Yousef, T. Heinemann, F. Rincon +5
Numerical simulations of forced turbulence in elongated shearing boxes are carried out to demonstrate that a nonhelical turbulence in conjunction with a linear shear can give rise…
Convection and the origin of Evershed flows in sunspot penumbrae
G. B. Scharmer, A. Nordlund, T. Heinemann
We discuss a numerical 3D radiation-MHD simulation of penumbral fine structure in a small sunspot. This simulation shows the development of short filamentary structures with horizo…
