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…

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 t…

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…
