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…

A Kinetic Model of Solar Wind Acceleration Driven by Ambipolar Electric Potential and Velocity-Space Diffusion
Maximilien Péters de Bonhome, Viviane Pierrard, Fabio Bacchini
Parker Solar Probe (PSP) observations have revealed that most of the solar wind acceleration occurs very close to the Sun. This acceleration is partly due to the global electric po…
