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…
Polarization properties of synchrotron sources from simulations of relativistic magnetohydrodynamic turbulence
Luca Del Zanna, Niccolò Bucciantini, Simone Landi
The emission from the relativistically hot plasmas of high-energy astrophysical synchrotron sources, pulsar wind nebulae (PWNe) in particular, depends on the level of magnetic fluc…
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…
The effects of expansion and turbulence on the interplanetary evolution of a magnetic cloud
Mattia Sangalli, Andrea Verdini, Simone Landi +1
Coronal mass ejections (CMEs) represent the most extreme solar products, showing complex and dynamic structures when detected in situ. They are often preceded by a shock and carry…
Temperature and density profiles in the corona of main-sequence stars induced by stochastic heating in the chromosphere
Luca Barbieri, Lapo Casetti, Andrea Verdini +1
All but the most massive main-sequence stars are expected to have a rarefied and hot (million-Kelvin) corona like the Sun. How such a hot corona is formed and supported has not bee…
