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…
Solar Wind Proton Heating and its Effect on Temperature Anisotropy Evolution between 0.05 and 1 au
Etienne Berriot, Arnaud Zaslavsky, Olga Alexandrova +3
This study focuses on the radial evolution of the solar wind proton adiabatic invariants and temperature anisotropies in the inner heliosphere. More specifically, we study in-situ…
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 the presence of an expanding magnetic field. We consider a stationary two-component plasma confi…
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…
Tearing Driven Reconnection: Energy Conversion Involving Firehose Kinetic Instabilities (2D Hybrid Möbius Simulations)
Etienne Berriot, Petr Hellinger, Olga Alexandrova +2
This study focuses on energy conversion related to tearing-driven magnetic reconnection in the context of weakly collisional astrophysical plasmas. We present results from a two-di…
Partial Null Point Reconnection of an Eruptive Filament
Pooja Devi, Cristina H. Mandrini, Ramesh Chandra +4
Solar filaments are cool and dense plasma structures suspended in the solar corona against gravity. We present observations of a quiescent filament eruption that occurs on 13 July…
