Spherically Polarized Alfvén Waves and the Gosling Boost
Yuliang Ding, Marco Velli, Zesen Huang +6
Alfvén waves are thought to play critical roles in solar wind acceleration and plasma heating in the solar corona and inner heliosphere. Parker Solar Probe (PSP) has highlighted th…
Solar Wind Proton Heating and its Effect on Temperature Anisotropy Evolution between 0.05 and 1 au
Etienne Berriot, Arnaud Zaslavsky, Olga Alexandrova +3
This study focuses on the radial evolution of the solar wind proton adiabatic invariants and temperature anisotropies in the inner heliosphere. More specifically, we study in-situ…
Evolution and Impact of Switchbacks Throughout the Heliosphere
Alfred Mallet, Chen Shi, Anna Tenerani +23
Magnetic switchbacks are large-amplitude fluctuations in the interplanetary magnetic field, and appear frequently in the near-Sun solar wind explored recently by Parker Solar Probe…
Magnetic switchback formation: a review of proposed mechanisms
Peter F. Wyper, Jonathan Squire, Etienne Pariat +19
Magnetic switchbacks are large amplitude deflections of the magnetic field within the solar wind. They are Alfvénic in character and so are associated with a spike in velocity and…
Generation and Expansion-Driven Growth of Switchbacks in the Outer Solar Corona and Solar Wind
Nikos Sioulas, Marco Velli, Chen Shi +6
We analyze \emph{Parker Solar Probe} and \emph{Solar Orbiter} measurements of magnetic-field reversals (``switchbacks'') across the Alfvén surface (), where is…
Evolution of an Alfvén Wave-Driven Proton Beam in the Expanding Solar Wind
J. S. Bianco, A. Tenerani, C. Gonzalez +2
We investigate the self-consistent formation and long-term evolution of proton beams in the expanding solar wind using an ensemble of one-dimensional hybrid expanding box simulatio…
