A Two-Population von Mises--Fisher Distribution of the Magnetic Field Direction in the Young Solar Wind
Gang Li, N. H. Bian, S. Y. Huang +6
The one-point distribution of the magnetic field direction in the young solar wind is found to be a superposition of two populations rather than a single exponential. Using Parker…
Reconstruction of photospheric velocity fields from highly corrupted data
Erico L. Rempel, Roman Chertovskih, Kamilla R. Davletshina +3
The analysis of the photospheric velocity field is essential for understanding plasma turbulence in the solar surface, which may be responsible for driving processes such as magnet…
Supergranular turbulence in a quiet Sun: Lagrangian coherent structures
Abraham C. -L. Chian, Suzana S. A. Silva, Erico L. Rempel +4
The quiet Sun exhibits a wealth of magnetic activities that are fundamental for our understanding of solar and astrophysical magnetism. The magnetic fields in the quiet Sun are obs…
On-off intermittency and amplitude-phase synchronization in Keplerian shear flows
Rodrigo A. Miranda, Erico L. Rempel, Abraham C. -L. Chian
We study the development of coherent structures in local simulations of the magnetorotational instability in accretion discs in regimes of on-off intermittency. In a previous paper…
Detection of coherent structures in photospheric turbulent flows
Abraham C. -L. Chian, Erico L. Rempel, Guillaume Aulanier +4
We study coherent structures in solar photospheric flows in a plage in the vicinity of the active region AR 10930 using the horizontal velocity data derived from Hinode/SOT magneto…
Coherent structures and the saturation of a nonlinear dynamo
Erico L. Rempel, Abraham C. -L. Chian, Axel Brandenburg +1
Eulerian and Lagrangian tools are used to detect coherent structures in the velocity and magnetic fields of a mean--field dynamo, produced by direct numerical simulations of the th…
Lagrangian chaos in an ABC--forced nonlinear dynamo
Erico L. Rempel, Abraham C. -L. Chian, Axel Brandenburg
The Lagrangian properties of the velocity field in a magnetized fluid are studied using three-dimensional simulations of a helical magnetohydrodynamic dynamo. We compute the attrac…
A novel type of intermittency in a nonlinear dynamo in a compressible flow
Erico L. Rempel, Michael R. E. Proctor, Abraham C. -L. Chian
The transition to intermittent mean--field dynamos is studied using numerical simulations of isotropic magnetohydrodynamic turbulence driven by a helical flow. The low-Prandtl numb…
