On hydromagnetic wave interactions in collisionless, high- plasmas
Stephen Majeski, Matthew W. Kunz
We describe the interaction of parallel-propagating Alfvén waves with ion-acoustic waves and other Alfvén waves, in magnetized, high- collisionless plasmas. This is accomplished…
Electron-ion heating partition in imbalanced solar-wind turbulence
Jonathan Squire, Romain Meyrand, Matthew W. Kunz
A likely candidate mechanism to heat the solar corona and solar wind is low-frequency "Alfvénic" turbulence sourced by magnetic fluctuations near the solar surface. Depending on it…
Magnetogenesis in a collisionless plasma: from Weibel instability to turbulent dynamo
Muni Zhou, Vladimir Zhdankin, Matthew W. Kunz +2
We report on a first-principles numerical and theoretical study of plasma dynamo in a fully kinetic framework. By applying an external mechanical force to an initially unmagnetized…
HelioSwarm: A Multipoint, Multiscale Mission to Characterize Turbulence
Kristopher G. Klein, Harlan Spence, Olga Alexandrova +47
HelioSwarm (HS) is a NASA Medium-Class Explorer mission of the Heliophysics Division designed to explore the dynamic three-dimensional mechanisms controlling the physics of plasma…
Cosmic ray transport in large-amplitude turbulence with small-scale field reversals
Philipp Kempski, Drummond B. Fielding, Eliot Quataert +4
The nature of cosmic ray (CR) transport in the Milky Way remains elusive. The predictions of current micro-physical CR transport models in magneto-hydrodynamic (MHD) turbulence are…
Local models of two-temperature accretion disc coronae. I. Structure, outflows, and energetics
Christopher J. Bambic, Eliot Quataert, Matthew W. Kunz
We use local stratified shearing-box simulations to elucidate the impact of two-temperature thermodynamics on the thermal structure of coronae in radiatively efficient accretion fl…
