Shear interaction and acceleration of a corotating stream detected by Parker Solar Probe
Andrea Verdini, Simone Landi, Emanuele Papini +4
Recent analysis of Parker Solar Probe (PSP) and Solar Orbiter data indicates that fluctuations energy is transferred to the bulk flow in fast streams of the solar wind at heliocent…
Radial and angular evolution of magnetic cloud signatures in the turbulent solar wind: virtual spacecraft analysis
M. Sangalli, E. K. J. Kilpua, A. Verdini +3
Interplanetary coronal mass ejections (ICMEs) carry magnetic clouds (MCs), large-scale structures with average radial widths about a fifth of an astronomical unit at Earth's orbit.…
Turbulent Heating between 0.2 and 1 au: A Numerical Study
Victor Montagud-Camps, Roland Grappin, Andrea Verdini
The heating of the solar wind is a key to understand its dynamics and acceleration process. The observed radial decrease of proton temperature in the solar wind is slow compared to…
Self-organization of local streamline structures and energy transfer rate in compressible plasma turbulence
Simone Benella, Virgilio Quattrociocchi, Emanuele Papini +4
We examine how local streamline topology and energy cascade rate self-organize in plasma turbulence for both compressible and incompressible regimes. Using a fully-compressible Hal…
On the Propagation and Damping of Alfvenic Fluctuations in the Outer Solar Corona and Solar Wind
Nikos Sioulas, Marco Velli, Chen Shi +17
We analyze \textit{Parker Solar Probe} and \textit{Solar Orbiter} observations to investigate the propagation and dissipation of Alfvénic fluctuations from the outer corona to 1~A…
Extended temporal coarse-graining in a stratified and confined plasma under thermal fluctuations
Luca Barbieri, Simone Landi, Lapo Casetti +1
We present an extended investigation of a recently introduced model of gravitationally confined, collisionless plasma (Barbieri et al. 2024a), which showed that rapid temperature f…
