A Nonlinear, Conservative, Entropic Fokker-Planck Model for Multi-Species Collisions
Evan Habbershaw, Cory D. Hauck, Jingwei Hu +1
A multi-species Fokker-Planck model for simulating particle collisions in a plasma is presented. The model includes various parameters that must be tuned. Under reasonable assumpti…

On a spectral method for -particle bound excitation collisions in kilonovae
Ryan T. Wollaeger, Chris L. Fryer, Robert Chiodi +9
The interaction of -particles with the weakly ionized plasma background is an important mechanism for powering the kilonova transient signal from neutron star mergers. For this…

Asymptotic Relaxation of Moment Equations for a Multi-Species, Homogeneous BGK Model
Evan Habbershaw, Ryan S. Glasby, Jeffrey R. Haack +2
Multi-species BGK models describe the dynamics of rarefied gases with constituent particles of different elements or compounds with potentially non-trivial velocity distributions.…
