Kinetic simulations of magnetic reconnection in presence of a background O+ population
Stefano Markidis, Giovanni Lapenta, Lapo Bettarini +3
Particle-in-Cell simulations of magnetic reconnection with an H+ current sheet and a mixed background plasma of H+ and O+ ions are completed using physical mass ratios. Four main r…
Self-consistent Seeding of the Interchange Instability in Dipolarization Fronts
Giovanni Lapenta, Lapo Bettarini
We report a 3D magnetohydrodynamics simulation that studies the formation of dipolarization fronts during magnetotail reconnection. The crucial new feature uncovered in the present…
Analysis of the energy release for different magnetic reconnection regimes within the solar environment
Lapo Bettarini, Giovanni Lapenta
A 2.5-dimensional magnetohydrodynamics simulation analysis of the energy release for three different reconnection regimes is presented. The system under investigation consists in a…
Three-dimensional evolution of magnetic and velocity shear driven instabilities in a compressible magnetized jet
Lapo Bettarini, Simone Landi, Marco Velli +1
The problem of three-dimensional combined magnetic and velocity shear driven instabilities of a compressible magnetized jet modeled with a plane neutral/current double vortex sheet…
Spontaneous non-steady magnetic reconnection within the solar environment
Lapo Bettarini, Giovanni Lapenta
This work presents a 2.5-dimensional simulation study of the instability of current-sheets located in a medium with a strong density variation along the current layer. The initial…
Magnetic Effects at the Edge of the Solar System: MHD Instabilities, the de Laval nozzle Effect and an Extended Jet
M. Opher, P. C. Liewer, M. Velli +6
To model the interaction between the solar wind and the interstellar wind, magnetic fields must be included. Recently Opher et al. 2003 found that, by including the solar magnetic…
