Magnetic null points in kinetic simulations of space plasmas
Vyacheslav Olshevsky, Jan Deca, Andrey Divin +5
We present a systematic attempt to study magnetic null points and the associated magnetic energy conversion in kinetic Particle-in-Cell simulations of various plasma configurations…
On the electron dynamics during island coalescence in asymmetric magnetic reconnection
Emanuele Cazzola, Maria Elena Innocenti, Stefano Markidis +3
We present an analysis of the electron dynamics during rapid island merging in asymmetric magnetic reconnection. We consider a doubly periodic system with two asymmetric transition…
Where should MMS look for electron diffusion regions?
G. Lapenta, M. Goldman, D. Newman +1
A great possible achievement for the MMS mission would be crossing electron diffusion regions (EDR). EDR are regions in proximity of reconnection sites where electrons decouple fro…
Energetics of kinetic reconnection in a three-dimensional null points cluster
Vyacheslav Olshevsky, Giovanni Lapenta, Stefano Markidis
We performed three-dimensional Particle-in-Cell simulations of magnetic reconnection with multiple magnetic null points. Magnetic field energy conversion into kinetic energy was ab…
Role of Z-pinches in magnetic reconnection in space plasmas
Vyacheslav Olshevsky, Giovanni Lapenta, Stefano Markidis +1
A widely accepted scenario of magnetic reconnection in collisionless space plasmas is the breakage of magnetic field lines in X-points. In laboratory, reconnection is commonly stud…
Energy dissipation in magnetic null points at kinetic scales
Vyacheslav Olshevsky, Andrey Divin, Elin Eriksson +2
We use kinetic particle-in-cell and magnetohydrodynamic simulations supported by an observational dataset to investigate magnetic reconnection in clusters of null points in space p…
