On the Role of Chapman's Hydrostatic Solar Wind Mechanism in Parker's Hydrodynamic Solar Wind Model
Announce Type: replace-cross Abstract: The role of Chapman's hydrostatic solar wind mechanism (resulting from a hydrostatic force balance condition) in Parker's hydrodynamic solar wind model is investigated by invoking the de Laval nozzle analogy for the production of flow acceleration in the latter model. The action of solar gravity in Parker's hydrodynamic solar wind model is shown to be geometrically equivalent to a enormalization of the actual wind channel area and the renormalization...
Wave instabilities in anisotropic regularized Kappa plasmas: New plasma dispersion functions and numerical validation
arXiv:2606.08331v1 Announce Type: new Abstract: Plasmas in space and astrophysical environments are frequently found in (quasi-)stationary states not in thermal equilibrium, indicated by velocity distribution functions (VDFs) featuring nonthermal characteristics, such as Lorentzian high-energy tails and kinetic (temperature and strahl/beam) anisotropies. For decades, in-situ observations of electrons and ions in the solar corona, solar wind or planetary magnetospheres have been modelled...
Lattice Boltzmann Methods for Compressible (Magneto)hydrodynamics
arXiv:2606.00641v1 Announce Type: new Abstract: The simulation of magnetohydrodynamic (MHD) flows presents a highly complex, tightly coupled transport problem that poses severe numerical and computational demands. Towards this, we propose a novel class of Lattice Boltzmann Methods (LBM) schemes capable of solving a wide range of transport equation systems with high computational efficiency and scalability. Our approach exploits the algorithmic structure of kinetic formulations to separately...
