Magnetic field kinks and folds in the solar wind
Anna Tenerani, Marco Velli, Lorenzo Matteini +18
Parker Solar Probe (PSP) observations during its first encounter at 35.7 have shown the presence of magnetic field lines which are strongly perturbed to the point that th…
The role of Alfvén wave dynamics on the large scale properties of the solar wind: comparing an MHD simulation with PSP E1 data
Victor Réville, Marco Velli, Olga Panasenco +18
During Parker Solar Probe's first orbit, the solar wind plasma has been observed in situ closer than ever before, the perihelion on November 6th 2018 revealing a flow that is const…
Propagation of Alfvén waves in the expanding solar wind with the fast-slow stream interaction
Chen Shi, Marco Velli, Anna Tenerani +2
We carry out two-dimensional magnetohydrodynamic (MHD) simulations of an ensemble of Alfvénic fluctuations propagating in a structured, expanding solar wind including the presence…
Fast Recursive Reconnection and the Hall effect: Hall-MHD Simulations
Chen Shi, Anna Tenerani, Marco Velli +1
Magnetohydrodynamic (MHD) theory and simulations have shown that reconnection is triggered via a fast "ideal" tearing instability in current sheets whose inverse aspect ratio decre…
Spectral signatures of recursive magnetic field reconnection
Anna Tenerani, Marco Velli
We use 2.5D Magnetohydrodynamic simulations to investigate the spectral signatures of the nonlinear disruption of a tearing unstable current sheet via the generation of multiple se…
Dynamic evolution of current sheets, ideal tearing, plasmoid formation and generalized fractal reconnection scaling relations
Alkendra Singh, Fulvia Pucci, Anna Tenerani +3
Magnetic reconnection may be the fundamental process allowing energy stored in magnetic fields to be released abruptly, solar flares and coronal mass ejection (CME) being archetypa…
An introductory guide to fluid models with anisotropic temperatures Part 2 -- Kinetic theory, Padé approximants and Landau fluid closures
P. Hunana, A. Tenerani, G. P. Zank +7
In Part 2 of our guide to collisionless fluid models, we concentrate on Landau fluid closures. These closures were pioneered by Hammett and Perkins and allow for the rigorous incor…
An introductory guide to fluid models with anisotropic temperatures Part 1 -- CGL description and collisionless fluid hierarchy
P. Hunana, A. Tenerani, G. P. Zank +7
We present a detailed guide to advanced collisionless fluid models that incorporate kinetic effects into the fluid framework, and that are much closer to the collisionless kinetic…
