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…

Temperature inversion in a confined plasma atmosphere: coarse-grained effect of temperature fluctuations at its base
Luca Barbieri, Emanuele Papini, Pierfrancesco Di Cintio +3
Prompted by the relevant problem of temperature inversion (i.e. gradient of density anti-correlated to the gradient of temperature) in astrophysics, we introduce a novel method to…
