Compressible Turbulence in the Near-Sun Solar Wind: Parker Solar Probe's First Eight Perihelia
Manuel Enrique Cuesta, Rohit Chhiber, Xiangrong Fu +10
Many questions remain about the compressibility of solar wind turbulence with respect to its origins and properties. Low plasma beta (ratio of thermal to magnetic pressure) environ…
Nature and Scalings of Density Fluctuations of Compressible MHD Turbulence with Applications to the Solar Wind
Xiangrong Fu, Hui Li, Zhaoming Gan +2
The solar wind is a magnetized and turbulent plasma. Its turbulence is often dominated by Alfvénic fluctuations and often deemed as nearly incompressible far away from the Sun, as…
Hybrid simulation of Alfvén wave parametric decay instability in a laboratory relevant plasma
Feiyu Li, Xiangrong Fu, Seth Dorfman
Large-amplitude Alfvén waves are subject to parametric decays which can have important consequences in space, astrophysical, and fusion plasmas. Though the Alfvén wave parametric d…
Evidence for Parameteric Decay Instability in the Lower Solar Atmosphere
Michael Hahn, Xiangrong Fu, Daniel Wolf Savin
We find evidence for the first observation of the parametric decay instability (PDI) in the lower solar atmosphere. Specifically, we find that the power spectrum of density fluctua…
On the Existence of Fast Modes in Compressible Magnetohydrodynamic Turbulence
Zhaoming Gan, Hui Li, Xiangrong Fu +1
We study the existence and property of Fast magnetosonic modes in 3D compressible MHD turbulence by carrying out a number of simulations with compressible and incompressible drivin…
Magnetic Energy Conversion in MHD: Curvature Relaxation and Perpendicular Expansion of Magnetic Fields
Senbei Du, Hui Li, Xiangrong Fu +2
The mechanisms and pathways of magnetic energy conversion are an important subject for many laboratory, space and astrophysical systems. Here, we present a perspective on magnetic…
Parametric decay of Alfvénic wave packets in nonperiodic low-beta plasmas
Feiyu Li, Xiangrong Fu, Seth Dorfman
The parametric decay of finite-size Alfvén waves in nonperiodic low-beta plasmas is investigated using one-dimensional hybrid simulations. Compared with the usual small periodic sy…
Heating of Heavy Ions in Low-beta Compressible Turbulence
Xiangrong Fu, Fan Guo, Hui Li +1
Enhancement of minor ions such as He and heavy ions in flare-associated solar energetic particle (SEP) events remains one of the major puzzles in heliophysics. In this work, we…
Hybrid Simulations of Positively and Negatively Charged Pickup Ions and Cyclotron Wave Generation at Europa
R. T. Desai, M. M. Cowee, H. Wei +4
In the vicinity of Europa, Galileo observed bursty Alfvén-cyclotron wave power at the gyrofrequencies of a number of species including K, O, Na, and Cl, indicatin…
Parametric Decay Instability and Dissipation of Low-frequency Alfvén Waves in Low-beta Turbulent Plasmas
Xiangrong Fu, Hui Li, Fan Guo +2
Evolution of the parametric decay instability (PDI) of a circularly polarized Aflvén wave in a turbulent low-beta plasma background is investigated using 3D hybrid simulations. It…
Nonlinear sub-cyclotron resonance as a formation mechanism for gaps in banded chorus
Xiangrong Fu, Zehua Guo, Chuanfei Dong +1
An interesting characteristic of magnetospheric chorus is the presence of a frequency gap at , where is the electron cyclotron angular frequency. Recent choru…
