Formation of Suprathermal Electron Populations in the Expanding, Turbulent Solar Wind
Maximilien Péters de Bonhome, Fabio Bacchini, Luca Pezzini +1
Nonthermal features are ubiquitously observed in electron velocity distribution functions in the solar wind, yet their origin in the collisionless, turbulent, expanding solar-wind…
Hybrid simulations of the proton beam instabilities in the young solar wind. The formation of hammerhead-like distributions
R. A. López, Shaaban M. Shaaban, M. Lazar +4
Parker Solar Probe (PSP) observations in the young solar wind reveal new properties of both plasma particle velocity distributions (VDs) and associated electromagnetic (EM) wave fl…
Generation of proton beams at switchback boundary-like rotational discontinuities in the solar wind
Rong Lin, Fabio Bacchini, Jiansen He +2
Alfvénic rotational discontinuities (RDs) are abundant in the inner heliosphere and can be used to model the boundary of switchbacks, i.e. Alfvénic magnetic kinks. To investigate…
Alpha Core-Beam Origin in Low- Solar Wind Plasma: Insights from Fully Kinetic Simulation
Luca Pezzini, Fabio Bacchini, Andrei N. Zhukov +2
In-situ observations of the fast solar wind in the inner-heliosphere show that minor ions and ion sub-populations often exhibit distinct drift velocities. Both alpha particles and…
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…
