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 (…
The Role of Magnetic Reconnection in Energizing Protons and Heavier Ions at the Heliospheric Current Sheet
Giulia Murtas, Xiaocan Li, Fan Guo +3
During near-Sun crossings of the heliospheric current sheet (HCS), Parker Solar Probe (PSP) observed populations of high-energy protons and heavier ions indicating possible energiz…
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…
Nature of Transonic Sub-Alfvénic Turbulence and Density Fluctuations in the Near-Sun Solar Wind: Insights from Magnetohydrodynamic Simulations and Nearly-Incompressible Models
Giuseppe Arrò, Hui Li, Gary P. Zank +2
Recent Parker Solar Probe measurements have revealed that solar wind (SW) turbulence transits from a subsonic to a transonic regime near the Sun, while remaining sub-Alfvénic. Thes…
Spatio-Temporal Energy Cascade in Three-Dimensional Magnetohydrodynamic Turbulence
Giuseppe Arrò, Hui Li, William H. Matthaeus
We present a new scale decomposition method to investigate turbulence in wavenumber-frequency space. Using 3D magnetohydrodynamic turbulence simulations, we show that magnetic fluc…
Large Scale Linear Magnetic Holes with Magnetic Mirror Properties in Hybrid Simulations of Solar Wind Turbulence
Giuseppe Arrò, Francesco Califano, Francesco Pucci +2
Magnetic holes (MHs) are coherent magnetic field dips whose size ranges from fluid to kinetic scale, ubiquitously observed in the heliosphere and in planetary environments. Despite…
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…
