Abstract

Under certain conditions an intense kinetic plasma jet is observed to emerge from the apex of laboratory simulations of coronal plasma loops. Analytic and numerical models show that these jets result from a particle orbit instability in a helical magnetic field whereby magnetic forces radially eject rather than confine ions with sufficiently large countercurrent axial velocity.

ON THE OBSERVATION AND SIMULATION OF SOLAR CORONAL TWIN JETS

Liu, Jiajia ; Wang, Yuming ; Zhang, Quanhao ; ... - Astrophysical Journal

We present the first observation, analysis, and modeling of solar coronal twin jets, which occurred after a preceding jet. Detailed analysis on the kinetics of the preceding jet reveals its blowout-jet nature, which resembles the one studied in Liu et al. However, the erupting process and kinetics of the twin jets appear to be different from the preceding one. Lacking detailed information on the magnetic fields in the twin jet region, we instead use a numerical simulation using a three-dimensional (3D) MHD model as described in Fang et al., and find that in the simulation a pair of twin jetsmore »« less

PLASMA JETS AND ERUPTIONS IN SOLAR CORONAL HOLES: A THREE-DIMENSIONAL FLUX EMERGENCE EXPERIMENT

Moreno-Insertis, F. ; Galsgaard, K. - Astrophysical Journal

A three-dimensional (3D) numerical experiment of the launching of a hot and fast coronal jet followed by several violent eruptions is analyzed in detail. These events are initiated through the emergence of a magnetic flux rope from the solar interior into a coronal hole. We explore the evolution of the emerging magnetically dominated plasma dome surmounted by a current sheet and the ensuing pattern of reconnection. A hot and fast coronal jet with inverted-Y shape is produced that shows properties comparable to those frequently observed with EUV and X-ray detectors. We analyze its 3D shape, its inhomogeneous internal structure, andmore »« less

Observation of self-binding turbulent fluctuations in simulation plasma and their relevance to plasma kinetic theories

Berman, R.H. ; Tetreault, D.J. ; Dupree, T.H. - Phys. Fluids; (United States)

Non-wave-like fluctuations of the phase-space density are observed in simulations of turbulent plasma. During decay from an initial state, the mean square fluctuation level decays at a much slower rate than that of an individual fluctuation. The distribution function of the fluctuation amplitudes becomes non-Gaussian (skewed) in favor of negative fluctuations. An enhancement in the aggregate fluctuation lifetime is also observed when the turbulence is driven by an external source. A model based on a collection of self-binding negative fluctuations, called phase-space density holes, can explain the observations. Collisions between holes produce hole fragments and lead to fluctuation decay. However,more »« less

Kinetic simulation of a plasma collision experiment

Larroche, O. - Physics of Fluids B; (United States)

The ionic Fokker--Planck code which was written for describing plasma shock wave fronts [M. Casanova [ital et] [ital al]. Phys. Rev. Lett. [bold 67], 2143 (1991)] is applied to model the collision of two plasmas in plane geometry. Improvements brought to the code for that purpose are described. The initial phase of the experiment during which the plasmas interpenetrate is accounted for by a simple fluid model, which yields qualitative insight into the phenomena at play as well as an initial condition to start the kinetic simulation. The kinetic results obtained in the stagnation and thermalization phases are discussed withmore »« less
