Collisionless stationary states of a stratified plasma in an expanding magnetic tube with stochastic heating
Luca Barbieri, Pascal Démoulin, Daniel Verscharen
We investigate the collisionless kinetic structure of the upper solar atmosphere in an expanding magnetic field. Building on established velocity-filtration models, we extend the s…
Collisionless and collisional kinetics of a plasma atmosphere with spatially and temporally intermittent heating at its base
Luca Barbieri, Pascal Démoulin, Filippo Pantellini
The solar corona exhibits a pronounced temperature inversion, with plasma temperatures increasing by nearly two orders of magnitude from the chromosphere to the corona. We investig…
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…
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…
Temperature inversion in a gravitationally bound plasma: Case of the solar corona
Luca Barbieri, Lapo Casetti, Andrea Verdini +1
The temperature of the solar atmosphere increases from thousands to millions of degrees moving from the lower layer (chromosphere) to the outermost one (corona), while the density…
