Hybrid codes (massless electron fluid)
D. Winske, Homa Karimabadi, Ari Le +3
Hybrid codes are widely used to model ion-scale phenomena in space plasmas. Hybrid codes differ from full particle (PIC) codes in that the electrons are modeled as a fluid that is…
Astrophysical explosions revisited: collisionless coupling of debris to magnetized plasma
Ari Le, Dan Winske, Adam Stanier +4
The coupling between a rapidly expanding cloud of ionized debris and an ambient magnetized plasma is revisited with a hybrid (kinetic ion/fluid electron) simulation code that allow…
On the background-gyroresonant character of the Bell instability
Martin S. Weidl, Dan Winske, Christoph Niemann
We show that the Bell instability, which is widely considered potentially important for cosmic-ray acceleration, is the low-frequency limit of a gyroresonant interaction between th…
How it cramps the flow: three regimes for the saturation of parallel ion-beam instabilities
Martin S. Weidl, Dan Winske, Christoph Niemann
Motivated by recent advances in laboratory experiments on parallel ion-beam instabilities, we present a theoretical framework for and simulations of their evolution towards shock f…
