Phase-Space Energy Transfer of Wave-Particle Interactions using the Field-Particle Correlation Technique and Linear Plasma Theory with JET-PLUME
Collin R. Brown, Gregory G. Howes, Kristopher G. Klein +1
The collisionless transfer of energy between fields and particles through wave-particle interactions is a fundamental process in space plasmas but remains incompletely characterize…
Plasma Instabilities in Arbitrary Distributions: Comparison between ALPS and BO
Xudong Guo, Huasheng Xie, Kristopher G. Klein +3
Determining accurate wave dispersion relations is a central problem in plasma physics. Recent advances have enabled the numerical computation of linear dispersion relation in plasm…
The Damping and Instability of Ion-acoustic Waves in the Solar Wind: Solar Orbiter Observations
Hao Ran, Daniel Verscharen, Jesse Coburn +6
Observations of solar wind velocity distribution functions (VDFs) commonly reveal fine-scale structures. These features strongly influence kinetic processes such as wave damping an…
Wave-particle equilibria with heavy ions in weakly collisional space plasmas
Nicolás Villarroel-Sepúlveda, Daniel Verscharen, Pablo S. Moya +2
Space plasmas are weakly collisional since characteristic time scales related to Coulomb collisions are much larger than those of Larmor gyration or wave--particle interactions. Th…
Solar Wind Heating Near the Sun: A Radial Evolution Approach
Yogesh, Leon Ofman, Kristopher Klein +19
Characterizing the plasma state in the near-Sun environment is essential to constrain the mechanisms that heat and accelerate the solar wind. In this study, we use Parker Solar Pro…
Velocity-Space Signatures of Energy Transfer for Ion-Acoustic Instabilities
Mahmoud Saad Afify, Kristopher G. Klein, Mihailo M. Martinović +1
Context. Observations by Parker Solar Probe (PSP) of electrostatic waves suggest that electrostatic instabilities, including the ion-ion-acoustic instability (IIAI) frequently obse…
How the Oblique Drift Instability Alters Solar Wind Heating and Constrains the Distribution of Solar Wind Observations
Mihailo M. Martinovic, Kristopher G. Klein, Leon Ofman +6
Ion-driven plasma instability thresholds, derived from linear theory, constrain the distribution of solar observations in parameter space, defining boundaries of stable plasma para…
Observational Constraints on the Radial Evolution of O Temperature and Differential Flow in the Inner Heliosphere
Yeimy J. Rivera, Kristopher G. Klein, Joseph H. Wang +15
Over decades of solar wind observations, heavy ions have been observed to have a higher temperature and flow faster than protons in the solar corona and heliosphere. Remote observa…
The Dielectric Response of Plasmas with Arbitrary Gyrotropic Velocity Distributions
Kristopher Klein, Daniel Verscharen
Hot and tenuous plasmas are frequently far from local thermodynamic equilibrium, necessitating sophisticated methods for determining the associated plasma dielectric tensor and nor…
Impact of Two-Population -particle Distributions on Plasma Stability
Mihailo M. Martinović, Kristopher G. Klein, Rossana De Marco +3
The stability of weakly collisional plasmas is well represented by linear theory, and the generated waves play an essential role in the thermodynamics of these systems. The velocit…
Nonlinear energy transfer and current sheet development in localized Alfven wavepacket collisions in the strong turbulence limit
J. L. Verniero, G. G. Howes, K. G. Klein
In space and astrophysical plasmas, turbulence is responsible for transferring energy from large scales driven by violent events or instabilities, to smaller scales where turbulent…
