Ion and electron heating during magnetic reconnection in weakly collisional plasmas

Ryusuke Numata N. F. Loureiro

JOURNAL OF PLASMA PHYSICS 81 Apr 2015 [Refereed]

Magnetic reconnection and associated heating of ions and electrons in strongly magnetized, weakly collisional plasmas are studied by means of gyrokinetic simulations. It is shown that an appreciable amount of the released magnetic energy is dissip...

AstroGK: Astrophysical gyrokinetics code

Ryusuke Numata Gregory G. Howes Tomoya Tatsuno Michael Barnes William Dorland

JOURNAL OF COMPUTATIONAL PHYSICS 229(24) 9347-9372 Dec 2010 [Refereed]

The gyrokinetic simulation code AstroGK is developed to study fundamental aspects of kinetic plasmas and for applications mainly to astrophysical problems. AstroGK is an Eulerian slab code that solves the electromagnetic gyrokinetic-Maxwell equati...

Bifurcation in electrostatic resistive drift wave turbulence

Ryusuke Numata Rowena Ball Robert L. Dewar

PHYSICS OF PLASMAS 14(10) Oct 2007 [Refereed]

The Hasegawa-Wakatani equations, coupling plasma density, and electrostatic potential through an approximation to the physics of parallel electron motions, are a simple model that describes resistive drift wave turbulence. Numerical analyses of bi...

Chaos-induced resistivity in collisionless magnetic reconnection

R Numata Z Yoshida

PHYSICAL REVIEW LETTERS 88(4) 045003 Jan 2002 [Refereed]

Magnetic null points act as scattering centers where particles describe chaotic orbits and the mixing effect increases the kinetic entropy. In an open system where convection of particles into/from the chaos region exists, the saturation of the en...
