The Ambipolar electric field in multispecies plasma atmospheres: effects of alpha particles and stochastic heating
Luca Barbieri, Pascal Démoulin, Daniel Verscharen
We investigate stationary states of a collisionless, gravitationally stratified plasma atmosphere composed of electrons, protons, and alpha particles by extending Pannekoek--Rossel…
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 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…
