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…

Complexity of magnetic-field turbulence at reconnection exhausts in the solar wind at 1 AU

Rodrigo A. Miranda, Juan A. Valdivia, Abraham C. -L. Chian +1

Magnetic reconnection is a complex mechanism that converts magnetic energy into particle kinetic energy and plasma thermal energy in space and astrophysical plasmas. In addition, m…

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…

Existence, uniqueness and analyticity of space-periodic solutions to the regularised long-wave equation

R. Chertovskih, A. C. -L. Chian, O. Podvigina +2

We consider space-periodic evolutionary and travelling-wave solutions to the regularised long-wave equation (RLWE) with damping and forcing. We establish existence, uniqueness and…

Edge of Chaos and Genesis of Turbulence

Abraham C. -L. Chian, Pablo R. Muñoz, Erico Rempel

The edge of chaos is analyzed in a spatially extended system, modeled by the regularized long-wave equation, prior to the transition to permanent spatiotemporal chaos. In the prese…

Chaotic saddles in nonlinear modulational interactions in a plasma

Rodrigo A. Miranda, Erico L. Rempel, Abraham C. -L. Chian

A nonlinear model of modulational processes in the subsonic regime involving a linearly unstable wave and two linearly damped waves with different damping rates in a plasma is stud…

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…

Nonintegrable Interaction of Ion-Acoustic and Electromagnetic Waves in a Plasma

Felipe B. Rizzato, Sergio R. Lopes, Abraham C. -L. Chian

In this paper we re-examine the one-dimensional interaction of electromagnetic and ion acoustic waves in a plasma. Our model is similar to one solved by Rao et al. (Phys. Fluids, v…
