On the von Karman-Howarth equations for Hall MHD flows
S. Galtier
The von Karman-Howarth equations are derived for three-dimensional (3D) Hall magnetohydrodynamics (MHD) in the case of an homogeneous and isotropic turbulence. From these equations…
Anisotropic turbulent model for solar coronal heating
B. Bigot, S. Galtier, H. Politano
Context : We present a self-consistent model of solar coronal heating, originally developed by Heyvaert & Priest (1992), in which we include the dynamical effect of the background…
Large-Scale Magnetic Field Re-generation by Resonant MHD Wave Interactions
S. Galtier, S. Nazarenko
We investigate numerically the long-time behavior of balanced Alfven wave turbulence forced at intermediate scales. Whereas the usual constant-flux solution is found at the smalles…
Multi-scale Hall-MHD turbulence in the solar wind
S. Galtier, E. Buchlin
Solar wind magnetic fluctuation spectra exhibit a significant power law steepening at frequencies f>1Hz. The origin of this multi-scaling is investigated through dispersive Hall ma…
Influence of the definition of dissipative events on their statistics
Eric Buchlin, Sebastien Galtier, Marco Velli
A convenient and widely used way to study the turbulent plasma in the solar corona is to do statistics of properties of events (or structures), associated with flares, that can be…
Small-scale turbulent dynamo - a numerical investigation
R. J. West, S. Nazarenko, J. P. Laval +1
We present the results of a numerical investigation of the turbulent kinematic dynamo problem in a high Prandtl number regime. The scales of the magnetic turbulence we consider are…
A simplified numerical model of coronal energy dissipation based on reduced MHD
E. Buchlin, V. Aletti, S. Galtier +3
A 3D model intermediate between cellular automata (CA) models and the reduced magnetohydrodynamic (RMHD) equations is presented to simulate solar impulsive events generated along a…
A weak turbulence theory for incompressible MHD
S. Galtier, S. V. Nazarenko, A. C. Newell +1
We derive a weak turbulence formalism for incompressible MHD. Three-wave interactions lead to a system of kinetic equations for the spectral densities of energy and helicity. We fi…
Statistical Study of Short Quiescent Times Between Flares
Sebastien Galtier
The study of the statistical distribution of short quiescent times ( 30 minutes) between solar flares has been investigated on a 1D MHD model. A power law behaviour is found w…
