Physics of Circular Polarized Ion-Scale Waves in Hybrid Simulations of Alfvénic Fluctuations
Hai Yang Harry Qian, Trevor A. Bowen, Carlos A. Gonzalez +5
Ion cyclotron waves (ICW) and fast magnetosonic/whistler waves (FMW) are fundamental electromagnetic modes at ion kinetic scales, yet their generation mechanisms and roles in plasm…
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…
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…
Properties of current sheets in two-dimensional tearing-mediated incompressible magnetohydrodynamic turbulence
Chen Shi, Marco Velli, Nikos Sioulas +1
It is well known that the nonlinear evolution of magnetohydrodynamic (MHD) turbulence generates current sheets. In the solar wind turbulence, current sheets are frequently observed…
On the Radial Evolution of the Solar Wind : The Source Alignment Method Applied to Parker Solar Probe and Solar Orbiter Observations
Jean-Baptiste Dakeyo, Tamar Ervin, Stuart Bale +10
The properties of the solar wind, as measured in situ throughout the heliosphere, depend both on the characteristics of its coronal source and on the intrinsic processes governing…
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…
