Stability Analysis of the Proton Hammerhead Distribution Observed by Parker Solar Probe: Linear Theory and Fully Kinetic Simulations under Idealised Conditions
L. Pezzini, J. L. Verniero, F. Bacchini +3
The non-adiabatic heating of the slow Solar Wind (SW) remains an open problem, with wave--particle interactions as a primary candidate mechanism. Novel in situ Parker Solar Probe (…
Modeling complex plasma instabilities in space plasmas - Three-component electron formalism of heat-flux instabilities
Dustin L. Schröder, Marian Lazar, Horst Fichtner +2
Despite the fact that electrons observed in situ in space plasmas have three major components-the quasi-thermal core, suprathermal halo, and strahl-the analysis of instabilities tr…
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…
Quasi-linear approach of bi-Kappa distributed electrons with dynamic parameter. EMEC instability
Pablo S Moya, Roberto E Navarro, Marian Lazar +3
In recent years, significant progress has been made in the velocity-moment-based quasi-linear (QL) theory of waves and instabilities in plasmas with nonequilibrium velocity distrib…
Decoding the formation of hammerhead ion populations observed by Parker Solar Probe
Shaaban M. Shaaban, M. Lazar, R. A. López +2
In situ observations by the Parker Solar Probe (PSP) have revealed new properties of the proton velocity distributions, including hammerhead features that suggest non-isotropic bro…
The role of the thermal properties of electrons on the dispersion properties of Alfvén waves in space plasmas
Nicolás Villarroel-Sepúlveda, Pablo S. Moya, Rodrigo A. López +1
Context. The transition from left-hand to right-hand polarized Alfvén waves depends on the wavenumber, the ratio of kinetic to magnetic pressure , temperature anisotropy, and io…
Fully Kinetic Simulations of Proton-Beam-Driven Instabilities from Parker Solar Probe Observations
Luca Pezzini, Andrei N. Zhukov, Fabio Bacchini +5
The expanding solar wind plasma ubiquitously exhibits anisotropic non-thermal particle velocity distributions. Typically, proton Velocity Distribution Functions (VDFs) show the pre…
The effect of heavy ions on the dispersion properties of kinetic Alfvén waves in astrophysical plasmas
Nicolás Villarroel-Sepúlveda, Rodrigo A. López, Pablo S. Moya
Context. Spacecraft measurements have shown Kinetic Alfvén Waves propagating in the terrestrial magnetosphere at lower wavenormal angles than predicted by linear Vlasov theory of e…
