Critical comparison of collisionless fluid models: Nonlinear simulations of parallel firehose instability
Taiki Jikei, Takanobu Amano
Two different fluid models for collisionless plasmas are compared. One is based on the classical Chew-Goldberger-Low (CGL) model that includes a finite Larmor radius (FLR) correcti…
Mach Number Dependence of Ion-scale Kinetic Instability at Collisionless Perpendicular Shock: Condition for Weibel-dominated Shock
Takuro Nishigai, Takanobu Amano
We investigate ion-scale kinetic plasma instabilities at the collisionless shock using linear theory and nonlinear Particle-in-Cell (PIC) simulations. We focus on the Alfvén-ion-cy…
A non-local fluid closure for modeling cyclotron resonance in collisionless magnetized plasmas
Taiki Jikei, Takanobu Amano
A fluid description for collisionless magnetized plasmas that takes into account the effect of cyclotron resonance has been developed. Following the same approach as the Landau flu…
A new framework for magnetohydrodynamic simulations with anisotropic pressure
Kota Hirabayashi, Masahiro Hoshino, Takanobu Amano
We describe a new theoretical and numerical framework of the magnetohydrodynamic simulation incorporated with an anisotropic pressure tensor, which can play an important role in a…
First-principles simulations of electrostatic interactions between dust grains
Hotaka Itou, Takanobu Amano, Masahiro Hoshino
We investigated the electrostatic interaction between two identical dust grains of an infinite mass immersed in homogeneous plasma by employing first-principles N-body simulations…
A Robust Method for Handling Low Density Regions in Hybrid Simulations for Collisionless Plasmas
Takanobu Amano, Katsuaki Higashimori, Keisuke Shirakawa
A robust method to handle vacuum and near vacuum regions in hybrid simulations for space and astrophysical plasmas is presented. The conventional hybrid simulation model dealing wi…
