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…
Radial Evolution of Near-Sun Magnetic Switchbacks Alfvenicity, Occurrence Rate, and Size
Xiaolei Li, Chen Shi, Yuliang Ding
Magnetic switchbacks, characterized by reversals of magnetic field direction, are widely observed in the inner heliosphere by Parker Solar Probe (PSP). With PSP reaching perihelia…
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…
Observations of Transition from Imbalanced to Balanced Kinetic Alfvénic Turbulence
Jinsong Zhao, Trevor A. Bowen, Stuart D. Bale +3
We report observations of solar wind turbulence derived from measurements by the Parker Solar Probe. Our findings reveal the emergence of finite magnetic helicity within the transi…
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…
