Extended theory of the Taylor problem in the plasmoid-unstable regime
Luca Comisso, Daniela Grasso, François L. Waelbroeck
A fundamental problem of forced magnetic reconnection has been solved taking into account the plasmoid instability of thin reconnecting current sheets. In this problem, the reconne…
Impact of electron temperature anisotropy on the collisionless tearing mode instability in the presence of a strong guide field
Camille Granier, Emanuele Tassi, Dario Borgogno +1
We derive and analyze a dispersion relation for the growth rate of collisionless tearing modes, driven by electron inertia and accounting for equilibrium electron temperature aniso…
Visco-Resistive Plasmoid Instability
Luca Comisso, Daniela Grasso
The plasmoid instability in visco-resistive current sheets is analyzed in both the linear and nonlinear regimes. The linear growth rate and the wavenumber are found to scale as $S^…
Formation of Plasmoid Chains in Fusion Relevant Plasmas
Luca Comisso, Daniela Grasso, François L. Waelbroeck
The formation of plasmoid chains is explored for the first time within the context of the Taylor problem, in which magnetic reconnection is driven by a small amplitude boundary per…
Gyrofluid analysis of electron effects on collisionless reconnection
Camille Granier, Dario Borgogno, Daniela Grasso +1
The linear and nonlinear evolutions of the tearing instability in a collisionless plasma with a strong guide field are analyzed on the basis of a two-field Hamiltonian gyrofluid mo…
Marginally Stable Current Sheets in Collisionless Magnetic Reconnection
Camille Granier, Dario Borgogno, Luca Comisso +3
Non-collisional current sheets that form during the nonlinear development of magnetic reconnection are characterized by a small thickness, of the order of the electron skin depth.…
