A Neural Operator Closure for Landau Damping in Electrostatic Plasma
Samuel Burles, Enrico Camporeale, Oreste Pezzi
We present a data-driven plasma fluid closure for both linear and nonlinear electrostatic Landau damping in one dimension. A Fourier Neural Operator (FNO) is trained online within…
Energetic particle-mediated interplanetary shocks observed by Solar Orbiter
D. Trotta, D. Lario, B. Reville +10
Context: In collisionless shocks, energetic particles can carry sufficient pressure to modify the upstream plasma and the shock structure itself, a regime often invoked in theories…
Transport of electrons in tangled magnetic fields
Daniel Verscharen, Natasha Jeffrey, Anton Artemyev +6
Cosmic magnetic fields are typically inhomogeneous and often highly tangled due to large-scale plasma flows, turbulence, and instabilities. If the variations in the magnetic field…
Numerical simulations of waves and turbulence in coronal loops: observables and spectra
Fabio Feraco, Francesco Pucci, Claudio Meringolo +11
We investigate numerically the time evolution of velocity and magnetic field fluctuations in a coronal loop, focusing on the dynamics due to both phase mixing and turbulent cascade…
Evidence of energy conversion in weakly collisional plasma during an interplanetary coronal mass ejection
Omkar Dhamane, Anil Raghav, Simone Benella +14
Intervals of enhanced turbulent fluctuations are typically less frequent within the magnetic cloud region of an interplanetary coronal mass ejection (ICME). We investigate two such…
Stochastic Heating in the Sub-Alfvénic Solar Wind
Trevor A. Bowen, Tamar Ervin, Alfred Mallet +7
Collisionless dissipation of turbulence is important for heating plasmas in astrophysical, space physics, and laboratory environments, controlling energy, momentum and particle tra…
