New closures for more precise modeling of Landau damping in the fluid framework
P. Hunana, G. P. Zank, M. Laurenza +5
Incorporation of kinetic effects such as Landau damping into a fluid framework was pioneered by Hammett and Perkins PRL 1990, by obtaining closures of the fluid hierarchy, where th…
Nonlinear firehose relaxation and constant-B field fluctuations
Anna Tenerani, Marco Velli
The nonlinear evolution of Alfvénic fluctuations in the firehose unstable regime is investigated numerically and theoretically for an anisotropic plasma described by the one-fluid…
Parametric decay and the origin of the low frequency Alfvénic spectrum of the solar wind
Réville Victor, Tenerani Anna, Velli Marco
The fast solar wind shows a wide spectrum of transverse magnetic and velocity field perturbations. These perturbations are strongly correlated in the sense of Alfvén waves propagat…
Marginal Stability of Sweet-Parker Type Current Sheets at Low Lundquist Numbers
Chen Shi, Marco Velli, Anna Tenerani
Magnetohydrodynamic simulations have shown that a non-unique critical Lundquist number exists, hovering around , above which threshold Sweet-Parker type statio…
Onset of fast "ideal" tearing in thin current sheets: dependence on the equilibrium current profile
Fulvia Pucci, Marco Velli, Anna Tenerani +1
In this paper we study the scaling relations for the triggering of the fast, or "ideal", tearing instability starting from equilibrium configurations relevant to astrophysical as w…
