Kinetic collisionless model of the solar transition region and corona with spatially intermittent heating
Luca Barbieri, Pascal Démoulin
We develop a three-dimensional kinetic model of the solar transition region and corona in which the plasma above the chromosphere is collisionless and embedded in a uniform magneti…
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…
Self-consistent generation of the ambipolar electric field in collisionless plasmas via multi-mode electrostatics
Luca Barbieri
In this work, we investigate the generation of the ambipolar electric field in a gravitationally stratified, collisionless plasma atmosphere. In such environments, gravity tends to…
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…
