Solar-Cycle Modulation and Photospheric Magnetic Control of Turbulence in the Young Solar Wind
Yanwen Wang, Rohit Chhiber, Arcadi V. Usmanov +2
The solar wind is an outflow of solar plasma that expands from the corona to fill the heliosphere. Its turbulence provides a pathway for non-adiabatic heating and acceleration, and…
Averaging Effects on the Solar Wind Alfven Mach Number: Implications for Switchbacks and Alfven Transition
Joshua Goodwill, Subash Adhikari, Francesco Pecora +10
Averaging techniques in solar wind measurements have been a longstanding subject of debate. Using Parker Solar Probe (PSP) observations from encounters 1 to 19, we investigate how…
Dynamical Age of Alfvénic Turbulence in the Solar Wind
Rohit Chhiber, Yanwen Wang, Arcadi V. Usmanov +1
An evolving turbulent flow such as the solar wind can be meaningfully characterized by its "turbulence age" -- an estimate of the number of nonlinear times that have elapsed during…
Noise in Synthetic and Solar Wind Data: Superposition Principles
Jiaming Wang, Francesco Pecora, Rohit Chhiber +3
The interplanetary magnetic field exhibits a distinctive spectral density from frequencies of around $\unit[10^{-6}]{Hz}$ to around $\unit[10^{-4}]{Hz}$, ranging from harmoni…
